iirc at some point i even found the code in Unity / CsRefernce but can't remember if it was an inline calculation or we had a nice method for that as well

so i tried this :

var fix = position.width - UnityEditor.EditorGUI.IndentedRect(position).width;
float step = UnityEditor.EditorGUIUtility.labelWidth - fix; //  position.width * 0.4f;
var rect = position; rect.x += step; rect.width -= step;

which is 1 or two pixels off visually , but it does seem to retain the same width ratio when the insepctor is being resized

[UnityEditor.CustomPropertyDrawer(typeof(Distribution))]
public class DistributionDrawer : UnityEditor.PropertyDrawer  {
    public override void OnGUI( Rect position, UnityEditor.SerializedProperty property, GUIContent label ) {
        if( GetPropertyHeight( property, GUIContent.none ) < 20 ) {
            var fix = position.width - UnityEditor.EditorGUI.IndentedRect(position).width;
            float step = UnityEditor.EditorGUIUtility.labelWidth - fix; //  position.width * 0.4f;
            var rect = position; rect.x += step; rect.width -= step;
            var value = property.FindPropertyRelative("value");
            rect.height = GetPropertyHeight( value , GUIContent.none );
            value.floatValue = UnityEditor.EditorGUI.FloatField( rect, value.floatValue );
        }
        UnityEditor.EditorGUI.PropertyField(position, property, label, true);
    }
    public override float GetPropertyHeight(UnityEditor.SerializedProperty property, GUIContent label) {
        return UnityEditor.EditorGUI.GetPropertyHeight(property);
    }
}

Basically subtracting 2 pixels off the fix variable results in perfect alignment

[gloomy chasm]

Not sure, but uhh, why not use a Prefixlabel...?

[tough cairn]

notice what im doing is "injectiing an input field to a serialized class that already has a toggle

[visual stag]

Also... use UIToolkit ☠️

[tough cairn]

never

U can see in the clip when I toggle the field CollapseState(?..)* the " injected " field disappears ( hence the < 20 check )

[gloomy chasm]

I'm with Vertx on this one, it would be so easy in UITK. Plus, IMGUI will be 'deprecated' at some point... you will join us!

[tough cairn]

The day this happen I will abended ship 🫡

[visual stag]

Enjoy calculating property height like a pleb

[tough cairn]

that's def not the way to keep your community intact , why so salty ?

[visual stag]

It's in jest

[gloomy chasm]

Yeah, just joking. Having done custom editor scripting with IMGUI for years. Having UITk to all the calculations for you is just so nice.

[indigo condor]

One day I was like you, but this wonderful community made me switch to UI toolkits and it was the best thing I could do 😁💯

[indigo condor]

Could someone take a fast look at this?

[chilly steeple]

I'm confused with what exactly what behaviour you're looking for

[indigo condor]

i need the Add Data boxhelp to always have the first column's height, adding a scrollview if it's necessary

[chilly steeple]

Aren't all columns the same height?

[indigo condor]

Yeah, but when I add data on the right one it get's bigger, and i don't want that to happen, i want it to make appear a scrollbar

here is a little video about how it currently works

[chilly steeple]

Ah I understand

[indigo condor]

something like that...

[chilly steeple]

Yes, trying to think of the best way to show you

working on a visualization

[indigo condor]

Take your time :>

[chilly steeple]

I think this will achieve what you want

[indigo condor]

Oh, so clear! lemme try :>

[chilly steeple]

orange panel should also have height set to auto

grow might not be neccessary on that panel

[indigo condor]

hmmm not working

and it's weird, there is an horizontall scrollview

when is chosen a vertical one

[chilly steeple]

make sure that panel (the green one in my drawing) has a sufficient width

and you can also, on your scrollview, set "horizontal scroller visibility" from auto to hidden

[indigo condor]

done... and it's the same 😦

Do you want me to pass you the package and you just try it?

[chilly steeple]

sure

what unity version you on?

[chilly steeple]

cool, im on 2022.3.22f so should be fine to test on my end with no differences in UITK versions

[alpine bolt]

You can use a "not so good hack". Get the left column height on a RegisterCallbackOnce<GeometryChangeEvent> and set the height inline

[alpine bolt]

The USS way is to

.fill-available-parent-height {
    height: 0;
    flex-grow: 1;
    min-height: auto;
}```

[indigo condor]

@alpine bolt and that i apply it to the left column?

just that?

I'm lost

[alpine bolt]

To the scroll view of the right

[indigo condor]

on the right there are not any scrollview...

[alpine bolt]

You mentioned a scroller, right?

That must be there already. There’s no way around that.

And to that scroller (which is a ScrollView element), you add that class that I wrote.

[chilly steeple]

Changing layout properties on GeometryChangedEvent is a bit ehh as it could become cyclic

[alpine bolt]

Cyclic?

[chilly steeple]

I'm pretty sure Unity advices against setting layout properties as response to a GeometryChangedEvent, as setting the height on the element in itself can/will trigger another GeometryChangedEvent on the panel

[alpine bolt]

And I’m pretty sure RegisterCallbackOnce only gets called once 🤔

It’s a lazy/edge case solution. I provided a USS option as well.

[peak bloom]

true, when not done carefully, yeah

it's very easy to be accidentally doing recursive call

[peak bloom]

such as this one particularly 👆 😂

what's dumb is that, it would not cause stackoverflow and can be pain to track down

how about to force the ScrollView's scrollbar to always be visible instead?

[chilly steeple]

Wouldn't work as the scroll view itself is growing limitlessly

Not much to scroll if all contents are in view

[peak bloom]

then set your Scrollview to be fixed size

[indigo condor]

I try

[peak bloom]

by this I mean in Percent so you won't need to deal with shrink/growing manually

like this :
Header => 20%
Body (where your scrillview is at) => 60%
Footer => 20%

[indigo condor]

just that doesn't work

[indigo condor]

i'll try that too

[peak bloom]

wait, did you enable the scrollbar to be always visible?

[indigo condor]

yeah

[peak bloom]

it should show, but none in your pic

no no

[indigo condor]

alr :>

[peak bloom]

yeah, it's just to give an effect that that particular are is in a scroll area

[alpine bolt]

Isn't this what you want?

[peak bloom]

another way is to set a fixed height to those that are too small in the scrollview a bit bigger than scrollview's container so it will show the scrollbar

[indigo condor]

yeah, and when the left column gets expanded the scroll area gets bigger

[alpine bolt]

just add the class I gave you earlier to the scroll view

[indigo condor]

to the right one, right?

[alpine bolt]

anything you do on the left side, the scroll view will shrink down to 0

yes

[indigo condor]

like this?

[alpine bolt]

yep

[indigo condor]

the same

😩

ohhhh it was that!

I love you! ❤️

[chilly steeple]

Nice

[chilly steeple]

So this was the solution?

@alpine bolt could you explain why/how this works?

Lemme absorb that knowledge

[alpine bolt]

I saw that the ScrollView always wanted to extend to display the whole content. So my logic was to make it shrink (height: 0) and then have it expand it when it has space (flex-grow: 1). The space is granted by its parent/container
min-height: auto actually does nothing in this case.

[indigo condor]

Is there any way to avoid that when the window is smoller than the content size?

[gloomy chasm]

flex-shrink

[alpine bolt]

or min-height

[severe wing]

here i can see "cel" in canvas

but in game i cant

why?

[alpine bolt]

@severe wing wrong channel

[severe wing]

2d tools yea?

[gloomy chasm]

This channel is about making your own tools. You want #📲┃ui-ux I think

[timid coyote]

can i inherit a class in uss?

.field-with-button
{
    width: 95%;
    height: var(--field-height);
}

TextField
{
    display: none;
}``` i want TextField to the the properties of field-with-button. my guess is `TextField .field-with-button` but it doesnt work

[alpine bolt]

Try removing the space between TextField and .field-with-button

[timid coyote]

it didnt work

also setting the display to none in uss doesnt modify the style.display.value, why?

[alpine bolt]

Do you have inline styles set?

[timid coyote]

nope

[alpine bolt]

can you explain better what are you trying to do?

[timid coyote]

i have a popup and a button when i press the button the popup display sets to none and the textfield sets to flex

public EditablePopupField(SerializedProperty integerProperty, 
            Action<List<TValue>> onAddElements, Action<string> onElementAdded) : base(integerProperty, onAddElements)
        {
            _onElementAdded = onElementAdded;
            Initialize(); Compose();
        }

        private void Initialize()
        {
            this.AddStyleSheet<EditablePopupField<TValue>, EditablePopupField<TValue>>();
                
            _popupField.AddClass("field-with-button");

            _textField = new TextField(DisplayName)
                .AddClass(Helpers.AlignedFieldClass)
                .AddKeyEvent<TextField, KeyDownEvent>(KeyCode.Return, OnTextKeyDown);

            _button = new ButtonWithImage("Plus", OnButtonClick);
        }
        
        private void Compose()
        {
            this
                .AddChild(_textField)
                .AddChild(_button);
        }```

@import "../../../Editor Utility/Editor/Helpers/Helpers.uss";

:root
{
    flex-direction: row;
}

.field-with-button
{
    width: 95%;
    height: var(--field-height);
}

TextField.field-with-button
{
    display: none;
}

ButtonWithImage
{
    width: 4.3%;
}```

i really dont understand why it doesnt work

[alpine bolt]

where exactly is it not working in this code?

I don't see you adding the .field-with-button to TextField

my guess it's that OnButtonClick

[timid coyote]

i get this

[timid coyote]

but whats why i have asked if i can inherit a class

[alpine bolt]

you want to hide text field, right?

[timid coyote]

yep

[peak bloom]

how can I deal with long dropdown, it's so long scrolling it will take at least 16 seconds to the bottom 😅

[alpine bolt]

TextField {
    display: none;
}

TextField.button-pressed {
    display: flex;
}``` wouldn't this work?

[gusty mortar]

Is there anything to split them ? Like categories ?

[gloomy chasm]

If you control it, add sub groups. Otherwise, just be sad.

[peak bloom]

I be sad then 😅 .. yeah I think I'll go with that option

[timid coyote]

dont think so, if u press again the button it should go to none

[peak bloom]

will do just that 👍

[timid coyote]

but i do that onto the button action

private void OnButtonClick()
        {
            this.SendChangeEvent(false, true);
            ToggleFields();
        }

private void ToggleFields()
        {
            _popupField
                .ToggleStyleDisplay()
                .TryFocus();
            
            _textField
                .ToggleStyleDisplay()
                .TryFocus();
        }

/// <summary>
        /// Toggle between DisplayStyle.Flex and DisplayStyle.None for <paramref name="target"/>.
        /// </summary>
        public static T ToggleStyleDisplay<T>(this T target) where T : VisualElement
        {
            var displayStyle = target.style.display.value;
            target.style.display = displayStyle switch
            {
                DisplayStyle.Flex => new StyleEnum<DisplayStyle>(DisplayStyle.None),
                DisplayStyle.None => new StyleEnum<DisplayStyle>(DisplayStyle.Flex),
                _ => new StyleEnum<DisplayStyle>(DisplayStyle.Flex)
            };

            return target;
        }```

[alpine bolt]

You're setting stuff inline... That's why it's not working.

[timid coyote]

why it shouldnt?

[gusty mortar]

Inline style bypasses/overrides stylesheet

[alpine bolt]

You're USS display properties will be overwritten by inline setting

[timid coyote]

ik but the display inline applies after i pressed onces on the button

[alpine bolt]

instead, just add or remove classes on ToggleStyleDisplay

also

var displayStyle = target.style.display.value;

if you want a current value, use resolvedStyle, not style

[timid coyote]

whats ToggleStyleDisplay?

didnt know that, thanks 😄

[alpine bolt]

your own function

[timid coyote]

oh

thanks a lot :DD

[alpine bolt]

Personally, I would do it something like this

        public static T ToggleStyleDisplay<T>(this T target) where T : VisualElement
        {
            if (target.ClassListContains("display-none"))
            {
                target.RemoveFromClassList("display-none");
            }
            else
            {
                target.AddToClassList("display-none");
            }
            return target;
        }```

@timid coyote

[gusty mortar]

You could even consider using ToggleInClassList("display-none") https://docs.unity3d.com/ScriptReference/UIElements.VisualElement.ToggleInClassList.html

[timid coyote]

but if the display is already none (in another uss), it wont work

[alpine bolt]

Yeah, nvm my brain fart. I knew that existed

[timid coyote]

not?

[alpine bolt]

True, but that seems like a bad and confusing design

There's always ways to avoid that

[timid coyote]

or if resolvedStyle.display.value is already none return

yea

u can have multiple stylesheets right?

on a single visual element

[runic current]

can someone help me on why Debug.Log(listOfTileProp); return null?

[minor cloud]

Your variable's name is written with lowerCase, while you're searching for an UpperCase variable.

[runic current]

what?

[minor cloud]

I mean l is not the same as L. Names have to match case.

[runic current]

where?

[minor cloud]

Oh wait, I actually looked at the wrong variable. 😓

[runic current]

well i guess i can start over

can someone help me how to ddisplay a list of list in unity editor?

[minor cloud]

Unity struggles with dealing with multidimensional arrays/lists. Such arrays are not serialized at all, which is why they're not displayed. You won't even find the data if you open the file manually in an editor. The common workaround here is to save the inner array/list in some serializable class/struct, and then create an array/list of those. Another workaround is to flatten the list/array to a 1-dimensional array/list and refer to its elements with a formula like this: [x + y * width]

It might be also the case why your FindProperty returns null - if 2-dimensional data structures are not serializable, then stuff like this won't work.

[runic current]

oh i see

[runic current]

omfg its work

[north sphinx]

Is there a support for generic property drawer classes?
For example
class Foo<T>
[CustomPropertyDrawer(typeof(Foo<>))]
class FooDrawer<T> : PropertyDrawer

[gloomy chasm]

yes

no

[CustomPropertyDrawer(typeof(Foo<>))] yes to this
class FooDrawer<T> no to this.

You can use the fieldInfo to get the generic type argument type iirc

[north sphinx]

ah

so I just declare normal and figure generics on my own

got it

[gloomy chasm]

Yup

[north sphinx]

I'm very confused how to get System.Object value out of SerializedProperty

I have SerializedReference inside

and it doesn't allow me to use managedReferenceValue property

    [Serializable]
    public class AbstractSerializableCollection<T> : IKek
    {
        [SerializeReference] public T[] collection;

it's basically this

I need to get IKek out of SerializedProperty this exists as

[waxen sandal]

I think that's set only?

[north sphinx]

I don't understand what that means

[waxen sandal]

As in you can't read from it

[north sphinx]

🤔

[waxen sandal]

Oh apparently they added it We’ve refined the API for working with managed references in the context of CustomEditors, including the option for read access to SerializedProperty.managedReferenceValue.

What's your editor code?

[north sphinx]

            var root = new VisualElement();
            var scrollView = new ScrollView(ScrollViewMode.Vertical);

            var countLabel = new Label("Impact count: 0");
            root.Add(countLabel);
            root.Add(scrollView);
            var collectionProperty = property.FindPropertyRelative("collection");

            scrollView.TrackPropertyValue(collectionProperty, OnCollectionChanged);

            OnCollectionChanged(null);

            root.Add(new Button(() =>
            {
                var kek = (IKek)property.serializedObject;
                kek.AddElement();
            })
            {
                text = "Add Element"
            });

public override VisualElement CreatePropertyGUI(SerializedProperty property)

[waxen sandal]

So where you actually accessing the serializedproperty?

[north sphinx]

property access

[waxen sandal]

What?

[north sphinx]

            root.Add(new Button(() =>
            {
                var kek = (IKek)property.serializedObject;
                kek.AddElement();
            })

[waxen sandal]

I mean the array element from collectionProperty

[north sphinx]

oh, don't mind it

I don't have issue with it

I only need to get my AbstractSerializableCollection value

[waxen sandal]

Where is your collection field defined

[north sphinx]

    [Serializable]
    public class AbstractSerializableCollection<T> : IKek
    {
        [SerializeReference] public T[] collection;

[waxen sandal]

AbstractSerializableCollection where is this used

[north sphinx]

in monobehaviours/scriptable objects

[waxen sandal]

Show me

[north sphinx]

    public class AbilityCollisionCheckAuthoring : PlayableAsset, IAbilityEvent
    {
        public AbstractSerializableCollection<IImpactBaker> impactCollection = new();

[waxen sandal]

That needs to be a serializereference

[north sphinx]

it's not supported on generic fields

[waxen sandal]

Right, so you can't get it without using reflection

[north sphinx]

how do I get it with reflection?

[waxen sandal]

property.serializedObject is AbilityCollisionCheckAuthoring probably?

[north sphinx]

it's unknown

it can be used anywhere

[waxen sandal]

So property.serializedObject.GetType().GetField(property.name).GetValue(property.serializedObject)

In this example it is AbilityCollisionCheckAuthoring

But this only works if it's directly in a Unityengne.object

[north sphinx]

bruh, how the hell odin does it

[waxen sandal]

If you nest it further, you have to go find the UnityEngine.Object and traverse the tree

Reflection

Anyways, why do you need to do this

Why do you need IKek

[north sphinx]

I want to call generic method out of it

with <T> stuff

[waxen sandal]

Why do you need to call a generic method

[north sphinx]

to have support of virtual overrides

[waxen sandal]

What does your method actually do?

[north sphinx]

creates dropdown menu which adds all supported types of abstract element

but that's just part of it

I'm trying with alternative path

but now I'm struggling with how to get collection type

out of collectionProperty

[timid coyote]

I cant inherit a class in uss

 _textField = new TextField(DisplayName)
                .AddClass(Helpers.AlignedFieldClass)
                .AddClass("field-with-button")
                .AddKeyEvent<TextField, KeyDownEvent>(KeyCode.Return, OnTextKeyDown);```
i want this textfield to have the same settings as field-with-button but also a display to none(but not to add it by hand in the souce code)
```css
.field-with-button
{
    width: 95%;
    height: var(--field-height);
}

TextField
{
    display: none;
}``` 
`TextField.field-with-button`(+without .field-with-button class added to the text)  looks like this

[north sphinx]

Any idea what's up? Trying to make custom drawer for array, but as soon as I modify it - all PropertyField for it act as empty VisualElements

                container.Clear();

                var collectionProperty = property.FindPropertyRelative("collection");
                container.TrackPropertyValue(collectionProperty, OnCollectionChanged);

                var arraySize = collectionProperty.arraySize;

                countLabel.text = $"Impact count: {arraySize}";

                for (var i = 0; i < arraySize; i++)
                {
                    var elem = collectionProperty.GetArrayElementAtIndex(i);
                    var cachedIndex = i;

                    var elemRoot = new VisualElement
                    {
                        style =
                        {
                            flexDirection = FlexDirection.Row,
                            justifyContent = Justify.SpaceBetween
                        }
                    };

                    var propertyField = new PropertyField(elem);

                    elemRoot.Add(propertyField);

                    elemRoot.Add(new Button(() =>
                    {
                        collectionProperty.DeleteArrayElementAtIndex(cachedIndex);
                        collectionProperty.serializedObject.ApplyModifiedProperties();
                        OnCollectionChanged(null);
                    })
                    {
                        text = "RemoveElement"
                    });

                    container.Add(elemRoot);

and it doesn't matter how exactly I modify - from within SerializedProperty code or via direct modification somehwere else

When I open inspector for the first time it looks like this

After adding element

huh, the fix would be

                    var propertyField = new PropertyField();
                    propertyField.BindProperty(elem);

instead of var propertyField = new PropertyField(elem);

[alpine bolt]

show the UIToolkit Debugger settings of the element you want to disappear

[gusty mortar]

Hi ! Is there something to use other than boxedValue to access the data of a SerializedProperty which I don't know the specific type in advance ? The only intel I have is that the propertyType is Generic.

[alpine bolt]

what are you trying to do exactly. Do you need to reach the type or something like that?

[gusty mortar]

I'm trying to listen to some change on a visual element that kinda works like the PropertyField from Unity (so which works with many different types). The issue is that boxedValue is sometimes... weird. Say I have a field that is supposed to hold a reference to something (like a struct, class, etc), the boxedValue will contain a GUID, but this GUID will have some errors.

So I was wondering if there was something other than boxedValue I could use to read the data

Sorry, it's kinda hard to explain because my team implemented some custom struct that can be stored as an asset reference ^^'

[alpine bolt]

lower on the right side. Can't see the style properties

[timid coyote]

i thought u wanted to see the classes

[minor cloud]

You can use switch statement. It will be messy if you want to handle multiple types, but it should be enough if you want to support only a few types. Example:

switch (serializedProperty.propertyType)
{
  case SerializedPropertyType.Boolean:
    bool boolValue = serializedProperty.boolValue;
    // do something
    break;
  case SerializedPropertyType.String  :
    bool stringValue = serializedProperty.stringValue;
    // do something
    break;
}

[gusty mortar]

Yeah, that's what I'm trying to avoid ^^'

[gloomy chasm]

I mean if you know the type (A UnityEngine.Object in this case, no?) you can just get that type

[alpine bolt]

What do you mean GUID? BoxedValue is presented as a System.Object type

[alpine bolt]

I have 50 helper methods that are all around doing stuff like this... It's not messy, it's... helpful

[gusty mortar]

Yeah, that's the issue with the custom stuff my team did, and I think I'll just have to find a workaround. I'll sound stupid, but the ref is displayed as an Object field, but isn't actually an Object... I thought it was normal behaviour to get a GUID in boxedValue but I assume it's some shenanigan caused by the custom stuff.

[gloomy chasm]

Hmm, I wouldn't be surprised if it was the guid

[gusty mortar]

And yeah, I can get the type through the SerializedProperty (and at the same time it's a string so.... not very helful)

[minor cloud]

I also have a code like this. This mess can be fine as long you don't have to edit it. 😅 Some scripts are meant to never be opened again.

[gloomy chasm]

What is it you are trying to do exactly? I assume you are making a PropertyDrawer for a custom class/struct? Are you able to share the property drawer or the class/struct?

[alpine bolt]

so you do property.boxedValue.GetType() and it shows as a UnityEngine.Object?

[gusty mortar]

Unfortunately, not allowed to share much code. But thanks anyway for the answer

[gusty mortar]

I'll have a look at it

[alpine bolt]

Feels like it should have been the first thing to do in that process 😅

[gusty mortar]

Yeah sorry, kinda overwhelmed with information at my place ^^' it's actually an object of type of my custom struct, which is not an Object

[alpine bolt]

also, if you use ref SerializedProperty and then do stuff like property.Next or property.NextVisiable, it will change the property. Before you do Next, you should property.Copy to a new var first.

just an FYI

[gusty mortar]

I knew it, but the reminder is very welcomed

[alpine bolt]

So the GUID is something they also custom made, it seems.

[gloomy chasm]

Let me clarify something. boxedValue should only be used in 2 cases.

1. you are doing something generic (rare).
2. you need to get the value of a POCO because it has to be passed to a method or you need to run a method in the POCO.

Otherwise, you should be using the .OBJECTTYPEValue properties (.stringValue, .floatValue, .objectReferenceValue etc.)

[alpine bolt]

have you gone down the inheritance?

[gusty mortar]

Yeah. I know boxedValue should be avoided as much as possible, but i'm in the 1st case scenario

I have to listen to some SerializePropertyChangeEvent without knowing in advance what it contains.

It could be a int, an array, a custom type, whatever

[gloomy chasm]

Why do you need to get the value of the changed SerializedProperty?

[gusty mortar]

There's a layer of serialization over the one from unity, which uses reflection to set data to handle what Unity can't. the problem is that sometimes it need to be in sync with what Unity handles, so if the serialized object change, I have to change the serialized data in our layer too. don't ask me why it's like this, it just is and I have to compose with what I have in front of me ^^'

But it's fine if my problem has no "smart" solution, I'll try another approach

[alpine bolt]

@gusty mortar boxedValue with a type cast will give you the object you want. It seems to me that the given object is the problem.

[gusty mortar]

You're probably right. When I added some break points, the GUID appeared to randomly change without visible reason (like 2 character of the GUID had been replaced with 0). I quickly looked online and found some guys saying boxedValue could mess with GUIDs and that's why I came here to check if something else could be used. Well, guess I'll have resume investigation as to why the GUID shifts. Thanks guys for your time anyway.

[elder wasp]

So i managed to change input ports, but outputs don't change?

NVM, i had forgoten to add the styles to my outputs too

[alpine bolt]

Well that seems a rather serious issue 🤔 Can you link that forum post?

[alpine bolt]

There must be something else going on. The display property of the TextField is not set from what I see in the debugger

[gusty mortar]

Now that I took a step back from the problem, I see that I misunderstood their initial statement. boxedValue doesn't mess with the GUID. The actual statement is that Unity doesn't serialize GUID by default, at least not AS a GUID, that's why boxedValue may not contain what's expected.
I could find multiple discussion about it yesterday, like this one from last year, but it looks like my rotten brain was not really receptive during the 1st read.

And I think that's part of my problem. I mean, you can mark a struct as serializable and Unity will try to do its job, but in my case I think my team changed the way their struct is serialized and in the end it is not completely handled by Unity, resulting in the inability to properly read the data through SerializedObject.

[alpine bolt]

As a last resort, you could try reflection

[fast jetty]

how do i add an image to my inspector window?

[flat bone]

What exactly do you want to achieve?

[tepid roost]

anyone know of a good work around for https://docs.unity3d.com/ScriptReference/EditorUtility.OpenFilePanel.html
not actually displaying the title when used from macOS

[gusty mortar]

Hi ! It's me again with some random shenanigan. Do people here have experience using GetDrawerTypeForType through reflection ?
It was working like a charm until a specific issue that returns null despite a drawer exist. Since it's an internal function of Unity, it's not easy to find any documentation ^^'
The type I'm testing is a PropertyAttribute with a CustomPropertyDrawer. Maybe it doesn't work for attribute, only for custom property drawer aimed at a type idk. If anyone has more info 🙏

[alpine bolt]

What information do you have?

[gusty mortar]

Wdym? On the method or what data I got access to?
Data wise I got a the attribute type called TypeRefAttribute and I use the function to check if a custom drawer exist.
Concerning the unity method, not much appart from the example I found online.

It "sees" other custom drawer I have, but this specific one seems to be invisible in the eye of the method

[alpine bolt]

        public static Type GetCustomPropertyDrawerType2(Type type)
        {
            var assemblies = AppDomain.CurrentDomain.GetAssemblies();
            var types = new List<Type>();
            foreach (var assembly in assemblies)
            {
                types.AddRange(assembly.GetTypes());
            }
            var propertyDrawerTypes = types.Where(t => typeof(PropertyDrawer).IsAssignableFrom(t)).ToArray();
            foreach (var drawerType in propertyDrawerTypes)
            {
                var customPropertyDrawerAttribute = drawerType.GetCustomAttribute<CustomPropertyDrawer>(true);
                var field = customPropertyDrawerAttribute.GetType()
                    .GetField("m_Type", BindingFlags.NonPublic | BindingFlags.Instance);
                if (field != null)
                {
                    if (field.GetValue(customPropertyDrawerAttribute) is Type fieldType && fieldType == type)
                    {
                        return drawerType;
                    }
                }
            }

            return null;
        }``` try this one for example. It's not optimized but it should work

[elder wasp]

Im making a custom editor window, but every time i get a domain reload, I lose reference to the focused scriptable object that was used to make the data, how can I avoid that?

[gloomy chasm]

Set the referenced field as [SerializeField]

[elder wasp]

Mmm, that didn't work

public class InfiniteLandsGraphEditor : EditorWindow
{
    TreeGeneratorView treeView;
    AssetSelectorView assetsView;

    [SerializeField]
    private VisualTreeAsset m_VisualTreeAsset = default;

    [MenuItem("InfiniteLands/Graph Editor")]
    public static void OpenWindow()
    {
        InfiniteLandsGraphEditor wnd = GetWindow<InfiniteLandsGraphEditor>();
        wnd.titleContent = new GUIContent("InfiniteLandsGraphEditor");
    }

    public void CreateGUI()
    {
        // Each editor window contains a root VisualElement object
        VisualElement root = rootVisualElement;        
        m_VisualTreeAsset.CloneTree(rootVisualElement);

        var styleSheet = AssetDatabase.LoadAssetAtPath<StyleSheet>("Assets/sapra.InfiniteLands.Visual/UIBuilder/InfiniteLandsGraphEditor.uss");
        root.styleSheets.Add(styleSheet);

        treeView = root.Q<TreeGeneratorView>();
        treeView.focusable = true; 
        treeView.Focus();

        assetsView = root.Q<AssetSelectorView>();
        OnSelectionChange();
    }

    private void OnSelectionChange(){
        TreeGenerator tree = Selection.activeObject as TreeGenerator;
        if(tree && AssetDatabase.CanOpenAssetInEditor(tree.GetInstanceID())){
            treeView.PopulateView(tree);
            assetsView.PopulateView();
        }
    }
}

TreeGenerator is the object and is stored inside TreeGeneratorView

Actually i think i know what's wrong

[gloomy chasm]

You need to add a [SerializeField] TreeGenerator tree; field to the editor window.

[elder wasp]

yup that worked

private void OnSelectionChange(){
    TreeGenerator tree = Selection.activeObject as TreeGenerator;
    if(tree == null)
        tree = lastTree;
    else
        lastTree = tree;

    if(tree && AssetDatabase.CanOpenAssetInEditor(tree.GetInstanceID())){
        treeView.PopulateView(tree);
        assetsView.PopulateView();
    }
}

changed to this and added the field

[quaint zephyr]

private void _OnSceneGui(SceneView view)
{
    using var scope = new EditorGUI.ChangeCheckScope();
    var transform = _visualObject.transform;
    var nextPosition = Handles.PositionHandle(transform.position, transform.rotation);

    if (scope.changed)
    {
        transform.position = nextPosition;
    }
}

When i move the handle in the scene view, the handle moves (which means that the object's position is indeed being updated. However the object itself doesn't move. If I move the handle and then click on the scene post processing toggle, the visual of the object will update, but only for that frame.
Is there something I must also call when the scope changes to ensure the object's visual get's updated as well?
Update: the visual object has HideFlags.HideAndDontSave, if I don't set that, then it updates just fine, but unfortunately becomes part of the scene hierarchy (which I don't want)

[lusty patrol]

Hello wanna ask
How do i get color from eyedropper tool on EditorGUI.ColorField unity editor window in runtime ? So i can always get color whenever i hover my eyedropper.

In my case, when i use eyedropper tool, my color on donut not immediately change but when i am not using eyedropper tool, the color on donut will immediately change. (I wanna when i hover while using eyedropper tool, my color on donut will be change immediately)

[alpine bolt]

There's tutorials for that on YouTube

ColorField is editor-only

[lusty patrol]

sorry what is the link/what is the name of the youtube ?

[alpine bolt]

hi, reposting from #archived-code-general
I am trying to do a simple mesh drawing using drawmeshnow (working with gizmos with materials) to make the 2d bounding box from a 3d (vertex defined) bounding box (not actual bounding box).
No matter what i do the shape will consistently be slightly offset and i cant figure out why
https://discussions.unity.com/t/drawing-a-screen-space-rectangle-with-graphics-drawmeshnow/12873 (closest thing to what i need i found)
the code isnt crazy its just a static shape
Then i use ```cs
Camera camera = SceneView.currentDrawingSceneView.camera;
//Translation using camera.WorldToScreenPoint
//Find Extremities like above
//Then using camera.ScreenToWorldPoint

Let me know if someone knows more

(i also dont use nearclipplane but rather nearclipplane +0.1f cause the face keeps clipping on the camera)

[gloomy chasm]

Well.. without seeing what 'slightly offset' means, and without seeing the code. It is kinda hard to even start to make a a guess what might be wrong.

[pure coral]

Camera camera = SceneView
Matrix4x4 boxMatrix = Matrix4x4.TRS(go.position, go.rotation, visualizingScale);
Mesh boundingMesh = EvaluateMesh(camera, boxMatrix);
DrawMeshNow(boundingMesh, Matrix4x4.identity);

Mesh EvaluateMesh(Camera camera, Matrix4x4 transform)

    {

    };

    return mesh;
}```

@gloomy chasm i dont believe im doing something critically wrong am i?

its quite straight forward

yet in the scene view camera we got a consistent wrong view

constantly offset by a small amount (the box behind, is using the same vertices as transformed vertices)

[gloomy chasm]

Can you show what it looks like?

[pure coral]

Expected

[gloomy chasm]

Ooh, that is more than a little off...

[pure coral]

IKR??

im at this for 5 days

its making me claw my eyes out

like why is it so off

xD

Wait wait wait, somehow talking about it gave me a profound understanding

[gloomy chasm]

So, my first thought of how to do it would be to iterate over each vertex in the mesh, convert the positions to screenspace. And then do comparisons to find the positions of the corners of the screen space rect.

[pure coral]

I fixed it...

man it was a random variable leftover

[gloomy chasm]

Nice, rubber ducking ftw

[pure coral]

my initial implementation had a billboard approach

and i was transforming the square by a bit

[pure coral]

It doesnt happen to just me right?

[gloomy chasm]

Not at all, that is why we have a term for it haha 😛

[pure coral]

xD man this is embarrasing, but great the problem is fixed all the same

and i retain bragging rights! (thanks all the same)

okay back to work

[gloomy chasm]

Nothing to be embarrassed about. I have done the same sort of thing.
(If you haven't heard of rubber duck debugging: https://rubberduckdebugging.com/)

[timid coyote]

i still cant figure out why my class isnt applying the settings it has. The visual element has the stylesheet, has the class attached to it, but it wont apply its settings

[gloomy chasm]

As a sanity check for you, I will say that it all looks okay. Which I guess isn't that helpful haha. My only advice would be to simplify your testing scenario. Maybe even just open a UIBuilder document and add your uss file to it there and test.

[timid coyote]

ill try that

but idk what to do more

[gloomy chasm]

Like just a text field with the display-none class, and add the uss attached.

[timid coyote]

i really dont understand and it doesnt make any sense

[gloomy chasm]

Yeah, it seems like it should be working. That is why you simplify to a point where it does work. And from there, you can slowly work your way back until it breaks.

It is possible, though unlikely that it could be an issue with the actually name of the class display-none could be getting parsed by the parser somewhere. So if it still doesn't work, could try just adding a .test class and try it with that

[timid coyote]

tried changing the name but nothing

[timid coyote]

it worked

[gloomy chasm]

Nice, my guess might be that it is getting overridden. maybe a control is setting the display from code, or something else. Anyway, you can work up from that point until you do something that breaks it.

Or it just keeps working and you are left to wonder why it wasn't working to start with hahaha

[timid coyote]

so i found the big problem for unity

:rooot
{
    --spacing: 4f;
}

.display-none
{
    display: none;
}

.display-flex
{
    display: flex;
}

.position-absolute
{
    position: absolute;
}

.position-relative
{
    position: relative;
}

.space-element
{
    width: var(--spacing);
    height: var(--spacing);
    
    align-self: center;
    flex-shrink: 0;
}

.child-space
{
    margin-bottom: var(--spacing);
}```

i had the spacing variable

if i remove all the appearences of it, it works

why? idk

[clear kite]

I'm not really familiar with ui toolkit but I'm quite positive it's not rooot. if that's not it, I have no clue

[timid coyote]

ups

nah still doesnt want to work

[gloomy chasm]

root isn't supported by uss

[timid coyote]

but it works

[clear kite]

also what is the f doing in 4f, sorry I'm just guessing random things, even my CSS knowledge is quite limited

[gloomy chasm]

ahh yeah that would be it

I am pretty sure

[timid coyote]

yea i think thats it

thanks both of u :DD

[gloomy chasm]

huh my mistake, looks like it is supported. I wonder when they added that.

[clear kite]

sometimes good guess is enough it seems 🙂

[timid coyote]

its quite old, i just got back into ui toolkit after a year, and it had root supported back then

[gloomy chasm]

Yeah looks like I was just mis-remembering. The docs have it all the way back in at least 2021.

[hollow ore]

I have components which have fields I control with gizmos — how to run some callback when the value changes either from inspector, from handle (writing to field) and from possibly other script modifying the value?

For example

class Circle : MonoBehavior {
  float radius;
  void WhenRadiusChanges() => NotifySomeOtherComponents();
}

// by using handles to edit
[CustomEditor(typeof(Circle))]
class CircleEditor : Editor {
  void OnSceneGUI() {
    // ...
    circle.radius = Handles.RadiusHandle(...); // should make Circle trigger WhenRadiusChanges()
  }
}

class Another : MonoBehavior {
  Circle circle;
  void ControlCircle() => circle.radius = 2; // should make Circle trigger WhenRadiusChanges()
}

[gloomy chasm]

Well, in the editor you should not be setting the radius field directly. Instead using SerializedProperty so you can undo/redo support, dirtying, and prefab override support.

As for setting it from other components. Just make radius a property with a prive serialized backing field. And call the raise change event from the setter.

[hollow ore]

If I use UI Toolkit (I;ll be using it for the first time) do I have to use SerializedProperty or do I use a setter?

[gloomy chasm]

SerializedProperty. Most VisualElements have a bindingPath property that you can set to the string path of the serialized property

[indigo condor]

Is there any kinda c# method that detect when the horizontall slider appears?

[pine gull]

So I have a monobehavior that has to store lots of data(yes its needed), so much so that selecting the gameobject with the script attatched in the inspector lags the editor
Is there any way to stop this from lagging so badly, even if the result is that nothing is drawn/no data is displayed in the inspector for the script?

[hollow ore]

yeah, just write a custom inspector with folds for a lot of data

how many elements are drawn?

[pine gull]

none
I dont care to see the data, but that data needs to be serialized for reasons

[hollow ore]

i.e. how massive is your mono behavior

[pine gull]

can go into the gigs of data at the extreme

[hollow ore]

and you need a mono behavior for that?

[pine gull]

unfortunately yes

its storing per-mesh data that is specific to each gameobject(extreme case here would be meshes with greater than 10-20 million triangles)

I dont need to see any of it
I just need it to exist

[hollow ore]

is this all needed to be serialized?

[pine gull]

mostly yes

and yes I know this sounds not very sane

the extremes of the gigs of data are very rare, but the fact that they exist means i need to e able handle them

[hollow ore]

I'm not sure why you need to serialize them though, it can be a huge nail to your coffin

[pine gull]

cuz I need it to exist between editor and play mode without saving to an external asset

[hollow ore]

if gigs of data get serialized, and serialization kicks in several times when assets reimport, then you potentially have several gigs of data getting read and written repeatedly for some reason

[pine gull]

these dont get saved as assets for a variety of reasons, that being one of them, they exist in the gameobjects and nowhere else

delete the gameobject, delete the data

but I cant move or transform any objects that have this script attatched due to the lag that appears when the inspector is painted(I assume) which is a huge problem

from what I read online, this issue mostly comes down to the frequent repaints of the inspector right?

[hollow ore]

maybe some kind of local cache data structure or something or local DB would be better for that

the lag you see is most probably the serializer + inspector, if these are gigs of data

[pine gull]

yeah my thoughts exactly
so I was wondering if there was just a way to force it to not interact with the inspector or something similar to prevent this

[hollow ore]

does the inspector even paint anything?

[pine gull]

currently I have an empty oninspectorGUI running so nope

here rn the editor is lagging hard btw

[hollow ore]

I mean if gigs of data then that's like thousands of possible UI lines, but I bet unity would crash with out of memory first

[pine gull]

I have most of them [hiddenininspector]

and its like 1-2 gigs at most

as anything more than that would be caused by more than like 20 million triangles for a single thing

[hollow ore]

is the mesh data per game object or per mesh?

[pine gull]

per game object

for reasons

I actually group together meshes, so they cant be cached

[hollow ore]

in my personal opinion, and this comes from a position of mostly guesswork of what you do, you may want to use binary data format that is unburdened by unity's serialization system, and one which can persist this data on launches as well as quickly find respective data by some unique game object id, for example GUID or something.

[pine gull]

hmmm unfortunately I cant really do that

[atomic sable]

Why's my property drawer not using the correct indent/x position? Is there something I need to add to it?

namespace TerraPunk.Editor

You could use a combination of property.propertyType == SerializedPropertyType.ArraySize, property.depth and manually setting EditorGUI.indentLevel to get an accurate position for those elements.

But it is indeed strange. An IMGUI guru needs to come forward

[atomic sable]

So create an inspector for this script to do that?

[alpine bolt]

No. Use that one.

Just copy what you got until you fix it.

[atomic sable]

hrm im not sure where to use the array size thing but ill try the property depth. Thing is the property drawer is drawn in other places so i cant just set the indent for this specific situation

It may just be a bug bc its nested so many times, it works fine when its in a list directly

[alpine bolt]

The Cost property is a serialized collection (ArraySize) and it will suffer further indentation.

[atomic sable]

Oh i understand what you’re saying now

Ok ill try

[indigo condor]

Hi there everyone... Does anyone knows how to read a dropdown from c#

[indigo condor]

I've tried all i've found... and nothing 😭

[alpine bolt]

https://docs.unity3d.com/ScriptReference/UIElements.PopupField_1.html

[quiet ridge]

I have imported Kronnect asset "Hightlight Plus" but I keep getting these errors because they inherit from Editor

[alpine bolt]

Use RegisterValueChangedCallback

[quiet ridge]

I have assembly definitions, and even tried editor only assembly definition references, but im not 100% sure what Im doing, does anyone have any insight in to how i can solve this?

[alpine bolt]

Try adding using Editor = UnityEditor.Editor;

[alpine bolt]

Place it inside the namespaces

I just hope the asset itself does not contain its own Editor class lol

If that is the case, use that using Editor = ThatNamespace.Editor;

[quiet ridge]

Im scared to say too soon, but I think this fixed it!

testing XD

Thanks so much for your help

it worked

[indigo condor]

is there any method to detect whenan horizontall scrollbar appear?

[elder wasp]

How can I keep the foldout so that It expands to the bottom instead of staying in the center, but with the buttons still in the center?

Found a way

[hollow ore]

can I use the properties in the serializedProperty instead of the fields?

this is my class I try to use:

[Serializable]
public class Property<T> : Property {
    public T DefaultValue { get; private set; }

    [SerializeField] private T propertyValue;

    public T Value {
        get => propertyValue;
        set {
            if (EqualityComparer<T>.Default.Equals(propertyValue, value)) return;
            propertyValue = value;
            NotifyPropertyUpdated();
        }
    }

    public override string ToString() => $"{DisplayName} ({InternalName}<{typeof(T)}>: {Value})";

    public Property(string InternalName, string DisplayName, T DefaultValue) : base(InternalName, DisplayName) =>
        this.DefaultValue = propertyValue = DefaultValue;

    public static implicit operator T(Property<T> self) => self.Value;
}

and the Property base class also has:

public event Action<Property>? onPropertyChanged;
protected void NotifyPropertyUpdated() => onPropertyChanged?.Invoke(this);

(disregard the unfortunate naming of the class as Property, it's a WIP name)

and I wanted to write both custom inspector with gizmos that control the Property

and allow for other scripts to update the value which would trigger an onPropertyChanged event

because in some other root component I subscribe to this event and react appropriately (update shader uniforms)

but when I use SerializedProperty in the inspector, I can only access the [SerializeField] private T propertyValue with serializedProperty.FindPropertyRelative('propertyValue'), i.e. only the field and not the Value property with custom get and set

and from what I see, the saw I would have to... basically duplicate the bit with listening to serialized property changes, probably with something like this:
https://docs.unity3d.com/2022.1/Documentation/Manual/UIE-create-a-binding-callback.html
or this:
https://docs.unity3d.com/2022.1/Documentation/Manual/UIE-Change-Events.html

I'm also wondering if I should maybe refactor this into simple value fields + INotifyPropertyChanged directly on the class + some kind of PropertyDescriptor which holds the `Internal/Display Name and DefaultValue, as those remain mostly static and could even be implemented with annotations on fields

[alpine bolt]

@hollow ore I honestly don’t understand what you are asking

My guess is that you are trying to create a layer between a serialized property and the editor code with this Property<T> class?

[hollow ore]

I'll try to rephrase this:
What would normally be a simple field on a mono-behavior, I wrap in a Property<T> which holds additional metadata and has a Value getter and setter with an event. I need it, because I need to both: a) collect and process the properties metadata by a "root" component on an ancestor game object and b) expose the value for other components to get and modify it, so that any modification triggers a propertyChanged event (which is an event with Property<T> argument, because the metadata of the property is what I need in subscribers_.

And what I also need to do is be able to update the value inside this Property<T> class using gizmos, so I used SerializedProperty in the custom inspector code for the full undo and multi-editing support. But in the inspector, when I find a a SerializedProperty to, let's say, a Property<float> radius declared in the class Sphere : MonoBehavior, I can only get and set value with of the plain field inside Property<float> using radiusProperty.FindPropertyRelative(), which doesn't trigger propertyChanged events. That's why I would like to use Value property (thus calling event) on a Property<T> class.

[hollow ore]

soo... can serialized property be bound to property, not backing field? So that it can go through validation/notifications defined in setters.

[alpine bolt]

AFAIK, no.

You could make some static functions inside Property<T> that calculate things in the runtime side and editor side equally and make the necessary adjustments

You'd need to have a bunch of helper methods that handle values generically. It's going to take some work

[lament kayak]

hello everyone, i am really new at editor development, i want to develop an editor tool like 2d collision shape editor. Users can draw some polygons on editor. What are the topics i need to read about initially? Thanks a lot for your help

[tough cairn]

Have anyone seen this one before ? My ScriptableSingleton doesn't save properly

[FilePath("ProjectSettings/QuickSelection.asset", FilePathAttribute.Location.ProjectFolder)]
class QuickSelectionSettings : ScriptableSingleton<QuickSelectionSettings>
{
    [System.Serializable] public class Item
    {
        public string name;
        public string filter;
        public GameObject[] selection;
        public int[] selectionGUIDs;
    }

    [SerializeField] public List<Item> m_Items = new List<Item>();

    public bool ignoreDisabled = false;

    public void SaveFile( bool asText ) => Save( asText );

    // test
    private void OnEnable() {
        Debug.Log("Loaded: " + GetFilePath() );
        foreach( var item in m_Items ) {
            foreach( var sel in item.selection ) Debug.Log( sel );
            foreach( var guid in item.selectionGUIDs ) Debug.Log( guid );
        }
    }
}

when i do a domain reload it looks like everything is working as inteded :

but that's not the case when i look at the asset file , which is apparent when closing and re-opening the editor . All the catched(?) data is being lost

( after closing and opening the project )

[tough cairn]

same thing when i change the FilePath to Assets/Settings/QuickSelection.asset 🤔

[tough cairn]

kinda odd , just checked shader graph settings Graphics/Packages/com.unity.shadergraph/Editor/ShaderGraphProjectSettings.cs and its using the same "method"

however its YAML file does actually have valid GUID's

%YAML 1.1
%TAG !u! tag:unity3d.com,2011:
--- !u!114 &1
MonoBehaviour:
  m_ObjectHideFlags: 61
  m_CorrespondingSourceObject: {fileID: 0}
  m_PrefabInstance: {fileID: 0}
  m_PrefabAsset: {fileID: 0}
  m_GameObject: {fileID: 0}
  m_Enabled: 1
  m_EditorHideFlags: 0
  m_Script: {fileID: 11500000, guid: de02f9e1d18f588468e474319d09a723, type: 3}
  m_Name: 
  m_EditorClassIdentifier: 
  customInterpolatorErrorThreshold: 32
  customInterpolatorWarningThreshold: 16

( notice how m_Script has a valid fileID and guid )

I also implemented k = settings.GetSerializedObject() and calling k.Update() , editor end check then k.ApplyModifiedProperties() , and finally settings.Save() in the GUI

but still no dice 🎲

Does the singleton has to be used exclusively with SettingsProvider ? What I'm trying to do here is to have a scriptable object without one , and is drawn in a custom editor window

[tough cairn]

Also tried giving default prefab path similar to how com.unity.netcode.gameobjects/com.unity.netcode.gameobjects/Editor/Configuration/NetcodeForGameObjectsProjectSettings.cs does it - but that didn't work either ... ( even tho it doesn't have a settings provider )

Editor/Mono/Inspector/LineRendererEditorSettings.cs is storing its asset in the Library folder( [FilePathAttribute("Library/LineRendererEditorSettings", FilePathAttribute.Location.ProjectFolder)] ) with Save as text set to false , tried this method , but that's not it .. ( this one also doesn't have a settings provider )

Is it possible to write a timeline style edtior using UI Toolkit(the retain mode GUI API)? Where should I start?

[steady pilot]

by timeline style editor I mean an editor tool with timeline scales&sliders/tracks&clips/context menu to add stuff. But I don't need other more complex functions of unity Timeline(the underlying playable API graph, the clip mix, etc.)

[thorny rock]

Hey, I have a short pedantic question about private/public variables. Here is my editor extension that helps me reduce the amount of set up I have to do manually:

public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();
        PlayingField playingField = target as PlayingField;
        if (GUILayout.Button("Set up notes"))
        {
            FroggoNote[] notes = playingField.gameObject.GetComponentsInChildren<FroggoNote>();
            for(int i = 0; i < notes.Length; i++)
            {
                NavMeshNote[] navMeshes = notes[i].GetComponentsInChildren<NavMeshNote>();
                GameObject[] navMeshGameObjects = new GameObject[navMeshes.Length];
                for(int j = 0; j < navMeshes.Length; j++)
                {
                    navMeshGameObjects[j] = navMeshes[j].gameObject;
                }

                notes[i]._NavMeshObjects = navMeshGameObjects;
                EditorUtility.SetDirty(notes[i]);
            }
        }
    }

I recently changed my notes._NavMeshObjects to private because there is no reason any other class should be able to access it. Now my editor script no longer works. Of course I can create a getter or a public GetNavMeshGOs() function but they would just exist to satisfy the editor extension. What would you do?

[full anchor]

Hi everyone, am wondering on the tech behind the Rendering Debugger and if it is possible to control it via a script? The purpose is to create a simple preset using an editor script in Unity. 😄

[gusty mortar]

Is your custom inspector targeted at the type FroggoNote ?

[thorny rock]

Not, at playing field, which is parent of all FroggoNotes. I do this because I want on button to fix everything instead of selecting all 20+ notes each level and clicking the same button 20+ times to set up each note individually. 🙂

[hollow ore]

(unrelevant recommendation: use UIToolkit)

maybe your editor crashes mid-function, have you investigated the logs?

[gusty mortar]

It's not a crash, it's just that their property is not accessible from the inspector anymore.

[hollow ore]

if that's what he meant by

Now my editor script no longer works
then indeed, I assumed nothing at all works

[gusty mortar]

Since you're trying to modify children of the actual object, I'd suggest to :

• grab all children Object in an array
• instantiate a SerializedObject that target this array of Object
• instead of modifying data the same way you would manipulate a monobehaviour at runtime, use SerializedProperty

[thorny rock]

Hmmm I see. I have not found a convenient way to work with arrays with SerializedProperties but I guess that's the best option. :/
Thanks.

[gusty mortar]

It won't be much of a difference actually. If I'm not mistaken, your FroggoNote is a MonoBehaviour, which is an Object.
So you could have something like this:

FroggoNote[] notes = playingField.gameObject.GetComponentsInChildren<FroggoNote>();
for (int i = 0; i < notes.Length; i++)
{
  using(var serializedNote = new SerializedObject(notes[i]))
  {
    SerializedProperty navMeshObjectsProperty = serializedNote.FindProperty("_NavMeshGameObjects");
    NavMeshNote[] navMeshes = serializedNote.target.gameObject.GetComponentsInChildren<NavMeshNote>();
    navMeshObjectsProperty.arraySize = navMeshes.Length;
    for(int j = 0; j < navMeshes.Length; j++)
    {
      navMeshObjectsProperty.GetArrayElementAt(j).objectReferenceValue = navMeshes[j].gameObject;
    }

    serializedNote.ApplyModifiedProperties();
    this.serializedObject.ApplyModifiedProperties(); // not even sure you need this actually, as you're modifying children objects
  }
}

I may be mistaken for the placement of this.serializedObject.ApplyModifiedProperties() tho'

[thorny rock]

Wow thanks! I'll give it a try. 🙂

[gusty mortar]

As I wrote it on Discord, there may be some typos 🥲

[thorny rock]

Well if fixing some typos is above my paygrade I have to change careers 😄

[thorny rock]

The code works (I had to fix a small typo though 😛 ), thanks a lot! I only made one small change:

var noteObject = serializedNote.targetObject as FroggoNote;
NavMeshNote[] navMeshes = noteObject.gameObject.GetComponentsInChildren<NavMeshNote>();

There is no option to do serializedNote.target.gameObject.GetComponentsInChildren<NavMeshNote>();, so I made a small step inbetween to get the gameObject of the serializedObject. 🙂

Now I'll rework this into a function that can take various components because I do something similar several times. 🙂

[gusty mortar]

Ah yeah. I wasn't sure about it to be honest, so nice catch 🙂 Glad it helped !

[gloomy chasm]

Not sure I follow exactly. But one, are you actually calling Save()? Two, if the GameObjects are in the scene, they will not be saved.

[thorny rock]

For anybody interested: I used @gusty mortars suggestion and wrote a function that takes a MonoBehaviour and a propertyname and takes all components of type T that are children of the MonoBehaviour:

void GeneralizedArrayReferencing<T>(MonoBehaviour arrayHolder, string propertyName)
    {
        using (var serializedObject = new SerializedObject(arrayHolder))
        {
            var targetObject = serializedObject.targetObject as MonoBehaviour;
            T[] behaviours = targetObject.gameObject.GetComponentsInChildren<T>();

            SerializedProperty serializedProperty = serializedObject.FindProperty(propertyName);
            serializedProperty.arraySize = behaviours.Length;
            for (int i = 0; i < behaviours.Length; i++)
            {
                serializedProperty.GetArrayElementAtIndex(i).objectReferenceValue = behaviours[i] as MonoBehaviour;
            }

            serializedObject.ApplyModifiedProperties();
        }
    }

Maybe somebody is looking for something similar.

[indigo condor]

Any ideas on how to apply these translations to UXML files? I've got this script to manage them... ```csharp
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.IO;
using UnityEngine;

namespace DataCraft
{
internal class LanguageManager
{
// ----- Nested Members
internal enum Language
{
Eng,
Spa,
Fre,
Ger
}

    // ----- Fields
    private static LanguageManager instance;

    private readonly Dictionary<Language, ReadOnlyDictionary<string, string>> localizations = new();
    private Language currentLanguage;

    // ----- Properties
    internal static LanguageManager Instance => instance ??= new();
    
    // ----- Constructor
    private LanguageManager()
    {
        ChangeLanguage(Language.Eng); // This shall be the last saved language
    }

    // ----- Public Methods
    internal string GetLocalizedString(string key)
    {
        var currentLocalization = localizations[currentLanguage];
        return currentLocalization.ContainsKey(key) ? currentLocalization[key] : throw new KeyNotFoundException();
    }

    internal void ChangeLanguage(Language newLanguage)
    {
        currentLanguage = newLanguage;

        if (!localizations.ContainsKey(newLanguage))
        {
            string jsonPath = Project.RootFolderPath + $"/Languages/{currentLanguage}.json";
            string json = File.ReadAllText(jsonPath);

            // Not sure if can deserialize to ReadOnlyDictionary. Gotta check it and change this if not possible.
            localizations[newLanguage] = JsonUtility.FromJson<ReadOnlyDictionary<string, string>>(json);
        }
    }
}

}

... both translation names and uxml object names are the same...

[gloomy chasm]

I would do it in the editor window after the UXML is loaded as a VisualElement tree. Just go through each translation and find the element with the same name.

Though, not sure if it is really worth it tbh. Most of the editor doesn't and can't support other languages anyway.

[indigo condor]

You mean that is weird that someone liked to use the asset in a different language than english or that it's just going to be a problem for some reason?

[gloomy chasm]

The first. Basically, the only thing in the whole Unity Editor that would be in that other language, would be your asset.

[indigo condor]

hahaha, there are special people for all xD... and appart from the real use that people could give that tool from the asset it's more like a challenge for me and to add one more option to it :>

Anyways, thank you so much for your help 💯

[gloomy chasm]

Totally get it, happy to help 🙂

[arctic solstice]

Why wont this script show up in the tools menu in the editor? https://hastebin.com/share/ijihojiyeq.csharp

[visual stag]

Presumably there's an error

[arctic solstice]

Unity isn't putting any errors in the console.

[gloomy chasm]

It's possible that it might be because it is called ShowWindow. But it shouldn't be the case.

[visual stag]

Make sure errors are not disabled in the console window, and perhaps try giving Unity a restart

[arctic solstice]

Just restarted unity, still cant find it

[arctic solstice]

Should i change the name?

[gloomy chasm]

Can't hurt to try. And if it still doesn't show up can you share a screen shot of the Tools menu? Just in case you are missing it or something.

[arctic solstice]

Still not showing: https://i.imgur.com/NXDv1Nk.png

Could this be why? [MenuItem("Tools/Search Material By Shader", false, 22)]

[visual stag]

What do you mean "this"? It looks fine

[arctic solstice]

"false" but it seems that wasn't it.

[visual stag]

It appears fine in my editor, so there's nothing wrong with the code

[arctic solstice]

Where did you put the files?

Did you put only the script?

[visual stag]

I just put the function declaration and menuitem in any old script

[arctic solstice]

So does that mean the script is the issue, not the code you took?

[visual stag]

I have absolutely no idea what the issue is, I can only presume the script hasn't compiled, or there's some Unity-specific version issue

[arctic solstice]

How could i force the script to compile?

oh i'm on 2021.3.6f1

[arctic solstice]

I figured it out, i had lots of scripts that had errors

[visual stag]

That would do it

[arctic solstice]

Sadly it was all for nothing, i was trying to fix all of the materials like this. https://i.imgur.com/QSdWq8E.png

[arctic solstice]

Do you know of a way i could fix all of materials fast?

I am very new to git

[timid coyote]

Is it possible to rearrange the elements in a scrollview?

[native geode]

I really like control custom property drawers gives with OnGUI which passes rect

How can i have same control with custom editor?

Like this button, i want to control its size (width, height), its color and so on

[visual stag]

You can use https://docs.unity3d.com/ScriptReference/EditorGUILayout.GetControlRect.html
Or https://docs.unity3d.com/ScriptReference/GUILayoutUtility.GetRect.html
Or some other methods to allocate some size in the layout and use the rect they return to do whatever you want in that space

You can also pass GUILayoutOption parameters to functions to override specifics without having to use rects

But imo all if it is way more flexible and easier in UITK and IMGUI-only things won't be compatible in a release or two.

[native geode]

Won't work on newer Unity versions?

Dropping compatibility? That means lots of packages might not work.

[visual stag]

Not now, but in a major release or two

UITK has been the main way to write editor scripts for quite a few major releases now

[native geode]

Iam doing IMGUI because UITK might have problems on version 2020 for example.

[visual stag]

That's a 4-year old unsupported release, but UITK also worked then

[native geode]

Iam really close to the release of the tool so I dont think it would be efficient to change everything now but thanks

Ill see how to work on button size

Yeah problem with lists

fixed it somehow 😅

basically it takes property height of last item in the list

so if you expand middle element it should look bad, right?

Hey I'm just looking for some pointers here I can't wrap my head around.

What's your thoughts on applying those translations to another Texture2D, the background image is 1 resolution the other could be different, larger or smaller etc.
Any ideas to bounce off would be nice, much appreciated in advanced. And a Terrible image for refference to help get my point across. im able to render the background image, a 3D model and the overlay image along with modifying the colors however im having a bit of an issue translating the overlay image position/scale to the rendered image. i took a peek into the render textures rect as well as the overlay rect as they seem to line up. im having some issues translating that data into a stored image. i was wondering if anyone has any pointers i could look at from a new angle.Hey I'm just looking for some pointers here I can't wrap my head around.

Hello guys, I want to share my unity project in github. But also I want other people see the codes that I wrote. When I build the project, I realise that they cannot see it in the build folders. So Is there any specific settings for that to handle it?

Codes that you wrote? what is your problem? You push project to the git but there is no source code?

[whole steppe]

Yes exaxtly @native geode

[native geode]

First, that is wrong channel, you should use #💻┃code-beginner
Second, can you share git link? Where are you initializing your git? it should be in your project folder and it should include gitignore so garbage doesnt get pushed

youre pushing built version on git?

[hollow ore]

Anyone knows some good patterns of handling scene gizmos/handles and serialized properties, so that they go beyond the basic "set value" but also "notify changes" etc?

Do SerializedProperty go beyond anything basic as setting the field?

I have some properties exposed with the system from Unity.Properties with [CreateProperty]

because I created some {get; set;} properties that emit events on changes

but looks like SerializedProperty... wasn't really designed to wotk with Unity.Properties, only fields (funny, given the name of the package 🙃)

@hollow ore you can read, write and track properties

You can also create dummy/temporary scriptable objects, to create property fields out of “thin air”

[hollow ore]

because "properties" here are ambiguous, let's differentiate between "auto/backed C# properties" (int X {get; set;}), "custom C# properties" (int X {get => doStuff(); set => DoOtherStuff(value);), "SerializedProperties" (from unity's SerializedProperty and SerializedObject) and "Unity.Properties" (Property, IProperty, IPropertyVisitor etc. from Unity.Properties package)

[alpine bolt]

It’s easy to handle that

On one hand you can track a property using RegisterValueChangedCallback or VisualElement.TrackProperty(fieldProperty, action) if you set anything in the inspector

Meanwhile you have the code side where your getSetProperty behaving the same way as the editor tracking code.

You’d have to check if the field itself is being drawn/focused or not to avoid having the logic run twice

@hollow ore

[hollow ore]

I'm not sure what you mean by "code side behaving the same way as the editor tracking code" and "checking if the filed is being drawn/focused to avoid having logic run twice"

[alpine bolt]

The code side is basically the properties with backed logic that you can’t access through Unity’s serialization

I don’t have a better name for it 😅

[hollow ore]

For reference, this is how my component roughly looks like for now:

class SphereController : Controller {
  [SerializeField] [DontCreateProperty] float radius = 1f;

  [CreateProperty] [ShaderProperty(Description = "Sphere readius")]
  public float Radius {
      get => radius;
      set => SetField(ref radius, value); // SetField is setting value and calling PropertyChangedEventHandler event (from INotifyPropertyChanged interface) defined in base class
  }

  // some internal code writing to `Radius`
}

[CustomEditor(typeof(SphereController), true)]
class SphereControllerEditor : ControllerEditor {
  SerializedProperty radiusProperty;

  public override VisualElement CreateInspectorGUI() {
      radiusProperty = serializedObject.FindProperty("radius"); // finding "Radius" instead doesn't work, no such serializedProperty. I would like to avoid depending on unexposed property and rather my writes went directly through `Radius` property
      return base.CreateInspectorGUI();
  }

  protected override void OnSceneGUI() {
    base.OnSceneGUI();
    var controller = (SphereController)target;
    using var scope = new EditorGUI.ChangeCheckScope();
    var radius = Handles.RadiusHandle(Quaternion.identity, controller.transform.position, controller.Radius);
    if (!scope.changed) return;
  
    controller.Radius = radiusProperty.floatValue = radius; // this is what I have to do currently to both emit an event and write to SerializedProperty
    serializedObject.ApplyModifiedProperties();
  }
}

and controller.Radius = radiusProperty.floatValue = radius; is subotmial, because I both, have to know radiusProperty, which depends on private field of the SphereController making the contract weak, the assignment is duplicated and it's depending only on my knowledge that Radius is triggering event as side effect

[alpine bolt]

You should handle radius set and set triggering logic separately. Not doing so results in that duplication.

It seems that you are trying to resist refactoring 😅

[hollow ore]

it would just be a duplication a level higher

and I would have to remember to notify each time I update the radius

this seems like an antipattern

if a class is INotifyPropertyChanged then it should act accordingly, i.e. when a property change ⇒ notify

it shouldn't be an external, decoupled component's responsibility to trigger change event on the behalf of SphereController imo

[alpine bolt]

Just track the property and run the controller methods you need 🤷‍♂️

[alpine bolt]

You can still run values through the controller for validation

[alpine bolt]

My guess to why the serialization system is designed like this, in a general way, is to allow undo/redo operations, ensure data consistency and allow full control over how objects are displayed and written.

Does anyone know the name of the scriptable object icon?

To use in a custom editor

found it, it's just "ScriptableObject Icon"

[idle tree]

Is it possible to read my keyboard hitting 'Enter' to submit this field, without needing to click the button? So far I haven't been able to get it to read a keypress

I am using the unity new input system but this is an editor thing so I think I don't want to read from there maybe yeah?

[idle tree]

        {
            // just hope the key was enter. 
            Submit(yourInput);
            Event.current.Use();
        }

hm somehow this is only being called on enter, but the KeyCode is none

[alpine bolt]

Are you using UIE or IMGUI?

[idle tree]

Oh uhh I am not sure, I am using the one that uses tons of methods like StartHorisontal() EndHorisontal

[crude current]

is this a place to ask questions bc idk whats going on but my compiler isn't showing errors and i have no clue what to do

i think it's got smth to do with what its saying in the console, which is

"Failed to find dotnet info from path, falling back to acquire runtime via ms-dotnettools.vscode-dotnet-runtime
The architecture of the .NET runtime (undefined) does not match the architecture of the extension (x64)."

but i dunno how to fix that

if someone can help please lmk

forget it i figured it out lmfao

does anyone know how/if I can achieve mouse wrapping/jumping with an EditorTool without using EditorGUIUtility.SetWantsMouseJumping() or User32.dll, since one only seems to work when holding left/right click and the other one is only for Windows

[steady pilot]

Hi all, how to preview animation in a custom editor window(UI Toolkit)?

[elder wasp]

Im running a unity job in the editor and I want to wait until its complete to call another method

While in the editor

How can I do that? because the update with [ExecuteAlways] only gets called during repaint

[gusty mortar]

Hi ! I need some IMGUI reminder. How am I suppose to display borders around a Box for example ? I used GUIStyle.border (https://docs.unity3d.com/ScriptReference/GUIStyle-border.html), but I suppose I didn't use it correctly as it doesn't display any border.

[gloomy chasm]

You cannot render procedural effects with IMGUI like a border. You would need to use UIToolkit instead of IMGUI for it.

All rendering in IMGUI is done via textures

[gusty mortar]

Yeah, I'm using IMGUI because of some compatibility issue, otherwise I'd use UIToolkit.
So I have no choice but to have an appropriate texture, thanks.

[waxen sandal]

IIRC border is for when you have a background texture and you want to repeat the middle section and only stretch the borders horizontally/vertically

You can also just render a black box behind your texture

Or some lines around the texture

[alpine bolt]

What issue is that? I’m curious

[gusty mortar]

Nothing special. I'm just working on some tools that were made before UIToolkit was introduced. In order not to redo everything, I have to stick with imgui.

Oh btw @alpine bolt I did not take the time to answer after you shared the code sample to find a property drawer. Your code worked but I found what the issue was (in between 2 projects, people moved the drawer code outside the assembly...). Thanks for sharing anyway 🙂

[alpine bolt]

Can’t you go through all of the assemblies?

[gusty mortar]

I could, but the file wasn't suppose to move in the 1st place. So instead of doing a costly operation, we put the file at the right place

[frozen cove]

Hi all, hopefully this is the right channel to ask.
**How can I define the order of these? **(See pic, highlighted in green)
I know I can use the order = # property in the attribute, but that only orders the bottom level options.

So apparently I should be able to use
[MenuItem("ISB", false, 0)]
It needs to be on a method declaration so I just put it on an empty static method, but that gets the error:
Ignoring menu item ISB because it is in no submenu!

[visual tiger]

could some body please help me ? its the 3th time that my toolset asset is rejected by asset store support team and all of things that they said is problems in marketing image! i changed all of them each time. i can't understand whats the problem in these images ? :((((
i dont know why they reject my tool
is there any body from asset store support team here ?!

[waxen sandal]

Guessing it's the police car

But no idea

[elder wasp]

hi

How can I make a property field appear or disappear according to an attribute attached to it? I have an attribute and through reflection i end up with a bool that says if it should show or not

The problem im having is trigering a redraw when the original value changes

I would like to trigger a redraw any time any value changes on that object, but im unable to do that

Im using Node and the GraphView so somewhere around there it should be

[hollow ore]

can I use a Vector3Field to display some other data type in inspector and when the vector3 drawer changes update the data accordingly?

for example I want 2 Vector3Fields, one for position one for rotation, and there should be a link to a serialized Matrix4x4 property

when position or rotation field changes, it sets the matrix TRS

and when matrix TRS changes, the properties update

[empty echo]

Hi, I'm new to using Unity Version Control. I've used Git and Perforce in the past. I am wondering what Checkout does for a file in UVC? Is it the same as locking a file?

[alpine bolt]

You can create property drawers for attributes.

Then just hide it or make it empty

[elder wasp]

The problem is updating it on change from a Node

Since there's no repaint, i just create it from scratch when making the node

But there's no function that gets called to recheck the attribute

[astral garnet]

Is this what you need? Scroll all the way down: https://docs.unity3d.com/ScriptReference/MenuItem-ctor.html

[frozen cove]

Potentially. 🤔
It says "Parent menus derive their priority value from their first defined submenu." but I don't know how to define the priority of anything other than the last bit of the path which performs the function.

My/Menu/Path/DoSomething

I'd love to know how to set the priority/order of "My" or "Menu" or "Path", all attempts have just errored.
Also, in case it's different, I'm doing this in the Project windows right click.

[astral garnet]

I see. I'm afraid it's not possible as of now and it depends on how we solve it internally 😦 .

Which at times just seems random 😄

[frozen cove]

Lol yeah, I thought it might be compile order or something as it's not even alphabetical.
Thanks for the support though 🙂

[frozen cove]

Perhaps like the " _g" tag we can include to create hotkeys we could have something like " _p#" to define priority on these.
Though it would get confusing as these paths are declared multiple times for each function in them.

[CreateAssetMenu(fileName = "Projectile Config", menuName = "Proj _p0/Weapons _p3/Projectiles _p2/Projectile Config")]
I like to organise like this so at least it'd be consistent:
[CreateAssetMenu(fileName = "Projectile Config", menuName = MenuPaths.Weapons.Projectiles.PROJECTILES + "Projectile Config")]

I'm not convinced on my idea, just a thought 🤔

[hollow ore]

Is there a "flat resizable circle" handle? Like a wire disc you can drag by the edge to change it's size

this page shows 2D handle but doesn't say how to do it 😅

[chilly steeple]

Anyone happen to know how to find all assets in the project that implement a certain interface?

[outer kraken]

^you can use reflection .. it should look somewhat like this (typing on phone, from memory):

Assembly.GetAssembly().GetTypes().Where(_type  => _type.IsSubclassOf(THE_INTERFACE_HERE));

but you gotta google that.. idk if IsSubclassOf works for interfaces, and you probably want to check for all assemblies

[gloomy chasm]

Do you mean ScriptableObjects or prefabs with a component?

[chilly steeple]

sorry, yes, scriptableobjects only

so let's say all scriptable objects that implement IMyInterface/IMyInterface<T>

[gloomy chasm]

You can try doing "t:IMyInterface" in the project search and see if it works. I don't remember.

[chilly steeple]

Tried that and doesn't return results

[gloomy chasm]

Otherwise you might try the new Unity Search window/API

[chilly steeple]

Advanced Search? I tried that too but also didn't give me results (that said I tested with the same filter string as the default asset search)

[gloomy chasm]

I don't remember if they index inheritance. If it doesn't then your only option is to add it as a custom index property. Otherwise you just have to iterate over every scriptableobject asset

[chilly steeple]

Sorry, I should have specified for ScriptableObjects in my assets folder, not the code classes themselves.

[gloomy chasm]

If they are not supported, you would need to add a custom object indexer iirc https://docs.unity3d.com/ScriptReference/Search.CustomObjectIndexerAttribute.html

[surreal delta]

why exactly do you need to do that?

is it for a system or just searching for assets

[chilly steeple]

for a propertydrawer popup displaying existing options

[surreal delta]

do you use UI toolkit?

[chilly steeple]

ah yes

[surreal delta]

you can have an object field and filter it by a certain interface, then i think when you open the selection window it will filter the project and scene objects by that interface

[chilly steeple]

I tried using an objectfield with typeof(IMyInterface) but this does not find or display any of my assets when the selection window is opened

[surreal delta]

huh, then i might remember wrong

i use that for my TypeFilter attribute and it filters the input to what i want but i didnt remember if the selection window was filtered as well

[chilly steeple]

Right, I will try again but I am pretty sure I had a correct implementation this morning with no results. Will let you know!

[hard vale]

[latent grail]

Hi all, so I'm taking the plunge and messing about a bit with a custom inspector, but I'm not sure how to get some public variables from the script I'm 'hooking into' to show up in the editor script to be able to assign them using GUILayout. Would anyone have any idea which GUILayout 'element' to use?

    public static Terrain currentTerrain;
    public static Texture2D splatMap;
    public static GameObject[] treePrefabs;
    public static GameObject[] detailMeshes;
    public static Texture2D[] detailTextures;

And what I have for the editor script so far.

    public override void OnInspectorGUI()
    {
        DrawDefaultInspector();

        SpudsTerrainTools terrainTools = (SpudsTerrainTools)target;

        GUILayout.Label("Trees Setup");
        GUILayout.BeginHorizontal();
        if(GUILayout.Button("Populate Trees"))
        {
            terrainTools.PopulateTreesFromFolder();
        }

        if (GUILayout.Button("Clear Trees"))
        {
            terrainTools.ClearTreeEditor();
        }
        GUILayout.EndHorizontal();
    }
}

[gloomy chasm]

Those are static, and Unity cannot serialize static fields. So even if you do have it so you can assign them in the inspector, they will not be there when the domain reloads (script change, enter playmode, close the editor, etc.), and will not be saved to any file (scene or ScriptableObject)

[latent grail]

Dang it. lol. Yep, my bad. Brain fart moment. lol.

Yeah that sorted it, thank you 🙂

[hollow ore]

Are inspector windows in UI Toolkit reused between same type of components when selection changes?

I have 2 game objects with some component X, and in obj1 some bool property is true and in obj2 it's false, I registered field change callback and I have a suspicion that it's called when I change selection between obj1 and obj2

still a bit more investigation ahead of me, but maybe if someone know if this is what's happening I could at least check that route

[frank bough]

I'm losing my mind trying to set up Unity VScode. Currently I have these extensions installed. Any help would be deeply appreciated!

C#
C# Dev Tools
Unity

I also have .NET 7.0.3

I want to be able to see live syntax or compilation errors with the red underline and the recommended fixes. Right now I have to close the file for these issues to show up in the console of the Unity editor

Here are things I have tried

-Restarting VScode
-Reinstalling the extensions
-Removed Dev Tools and Unity (since Unity is dependent on Dev Tools), turned dotnet.server.useOmnisharp TRUE, turned omnisharp.useModernNet FALSE
-Confirmed in terminal I have .NET 7.0.3
-Tried the "OmniSharp: Restart OmniSharp" in command pallette, didnt even have that command
-Used different output screens to see if OmniSharp is installed, but there are no signs in these menus that it is

Omnisharp is only present in any form for me in extension settings, not ever in my file. Do I need to somehow make this file part of a VS project? Right now it is just a standalone script I made in unity.

omg omg i got it to work

omg

nvm

thanks for all your help tho

[hollow ore]

you could at least write what you did to make it work, so others in the future searching for the same problem could try your solution 😅

[tulip epoch]

How can I use FindPropertyRelative with inherited classes? Is this possible?
I saw something about using [SerializeReference] but I don't really understand it.

I'm trying to make a Property drawer that changes based on which inherited class is used.

[lament trail]

Let's see what you've trief

[tulip epoch]

I have a class with a field as such

[SerializeReference] private VariableValue constant;

VariableValue has a child class BoolVariableValue which store a bool.
I've been trying to access that bool property by:

var value = property.FindPropertyRelative("constant.value");
EditorGUI.PropertyField(rect, value);

The property value does not exist on the base class. Only the derived class. So this comes up as null.

[rain loom]

Hey, I have a little question

I wanted to export a package but it says this:

How can I just ignore it or can I find somehow things that are really not necessary?

[stoic vigil]

Hi! I'm generating a sort of grid in play mode, where each cell is a separate gameobject (child of the generator), with a generated mesh. I want to save this generated map for easier prototyping, but I'm not so sure how to go about it? Saving the parent object as a prefab, and saving all the individual meshes, does actually properly store the references to the meshfilter, but all the other fields are entirely empty (material, mesh collider). Any ideas on how to do this?

[safe sorrel]

I need to do a migration. Bascially, I want to go from this..

[System.Serializable]
public class Foo {
  public int whatever;
}

...to this...

[System.Serializable]
public class Foo {
  public int whatever;
  public bool workCorrectly = true;
}

I have lots of serialized copies of Foo. Just adding a new property with a field initializer doesn't cut it here.

The first thing that came to mind was to use reflection to look for all instances of the type and update them on the C# side. However, I'm thinking I should be looking at using SerializedObject/SerializedProperty to do this from the Unity side.

All of these instances are attached to components that are inside of prefabs. I can easily get all of the prefabs from the AssetDatabase.

So should I do something like this?

• Get all relevant prefabs
• For each prefab, use GetComponentsInChildren to find all of the relevant components
• For each component, construct a SerializedObject, then iterate over its properties (and over all of the items in the array properties)
• For each property, check if it's a Foo; if so, find its workCorrectly property and set it to true

[gloomy chasm]

Not sure I follow what the issue is?

[safe sorrel]

If I just update the code, all existing instances will have workCorrectly unchecked.

I need them all to wind up checked.

true will correspond to the existing behavior (which I want to keep on all existing instances of the class)

I also have other places that I want to do "migrations" on

e.g. I have a List<string> that I want to convert into a List<SomeOtherType>

so I will need to write editor code that updates every single existing component

I know a fair bit about reading data through reflection, but I'm a little flaky on writing data through reflection

(I'm trying to make a game without spending 30 hours bikeshedding every single part of it. this has resulted in a lot of content that will need updating when i eventually bikeshed it anyway 🙂 )

[short tiger]

In this specific case, I would think that any instances where there is no serialized value for the new field, the default value will be used. That's been my experience when adding new serialized fields.

[safe sorrel]

..ah, yes, that is the case. maybe i reloaded unity before i actually added the field initializer...

oops

Perhaps it's important that I'm in a prefab variant.

or that this is a list of the aforementioned class

I know that Unity just copies an element when you increase the size of a list

[safe sorrel]

argh, yeah, that's it. how annoying.

nothing gets any default values

the actual class here looks like this:

public class DialogueOption {
  public string text;
  public bool chosen;
  public Choice choice;
}

If choice says that it's been picked and chosen is true, the dialogue is valid. If choice says that it's not been picked and chosen is false, the dialogue is valid

most of my existing dialogue is for the former case

[short tiger]

Many of these types of migrations I've done with a Find & Replace in Files in Notepad++, with a Regex expression if I'm feeling fancy.

[safe sorrel]

i have done some major revisions by editing serialized data directly, yes (:

[safe sorrel]

My main concern is that I'm...a little unclear on how to dirty prefabs correctly

the unity documentation has a huge pile of methods

[gloomy chasm]

What do you mean when you say 'dirty a prefab' in this case?

[safe sorrel]

so there are two possibilites here:

• I modify some SerializedProperty data
• I modify the "real data" (so, assigning to fields) and then have to tell Unity to reserialize the objects

[safe sorrel]

suppose I have this

public List<string> oldData;
public List<MyCoolClass> newData;

and I want to achieve this:

newData.AddRange(oldData.Select(item => new MyCoolClass(item));

create new instances of MyCoolClass that are stored in newData based on the strings found in oldData

Then I would remove oldData from the class definition.

I would want to do this to many prefabs, all at once.

[gloomy chasm]

Are there prefab variants?

[safe sorrel]

Yes.

There could be arbitrarily nested prefab variants here.

[gloomy chasm]

Hmm, right

[safe sorrel]

i have one chain of four variants

it sounds like I'd need to start from the deepest prefab and work outwards?

the problem just got much more complicated now that you've reminded me about variants :p

[gloomy chasm]

Okay @safe sorrel what if you did this. Tried to disable asset importing which I think would prevent overrides maybe... and then set them.

Another option is maybe use GetPropertyModifications to get check if a property is modified, and if it is use ApplyPropertyOverride... maybe... I didn't fully read the docs and am kind of spitballing here.

https://docs.unity3d.com/ScriptReference/PrefabUtility.GetPropertyModifications.html
https://docs.unity3d.com/ScriptReference/PrefabUtility.ApplyPropertyOverride.html

[safe sorrel]

So I would 100% need to be working with SerializedObject and SerializedProperty here -- not directly modifying objects

[gloomy chasm]

Yeah. That is the only way I know to set modified properties on prefabs

[safe sorrel]

that makes sense, since the C# object has zero idea about prefabs

I use reflection to dig through prefabs (including prefab variants), but it's strictly read-only

[gloomy chasm]

You could try looking at the YAML to see if you can understand where overrides are stored, and manually insert it and edit the file directly

[safe sorrel]

(i wrote a bunch of validators to make sure i do not forgor to assign references)

okay, now for the punchline: i'll need to figure out how this interacts with [SerializeReference]

that may be the point where I just go edit the YAML

[gloomy chasm]

Oof yeah, it depends if you are actually reference them else where or just using it for the polymorphic serialization

[safe sorrel]

Strictly the latter so far.

[gloomy chasm]

Oh that makes it easier at least

If you haven't already give this a +1 maybe someday we will get it https://portal.productboard.com/z8pw2ms6jxytyez9chlmm4kr/c/578-c-serialized-data-migration?&utm_medium=social&utm_source=starter_share

[safe sorrel]

so if the base prefab has five strings in oldData and the new prefab has ten strings in oldData (including a few modified strings), I'd want to first create five entries in the newData property of the base prefab, then create overrides in the new prefab

[gloomy chasm]

sounds right

[safe sorrel]

ideally i could write this so that I just give it a function to run on each pair of old and new properties

[tulip epoch]

Uhh I'm having a very weird issue. Not sure how to properly explain it either. I'm trying to use EditorGUILayout.PropertyField(prop) to draw data from a selected array element from my Inspector GUI.

But this doesn't seem to update when the selecting a different array element. It only ever updates when I deselect the entire game object, and select it again.

At first I thought the selected property wasn't getting updated correctly, but going through a debug, it definitely is. It's just not being drawn?

[gloomy chasm]

How are you getting the selected. Can you show more of the code?

[tulip epoch]

Oof, it's quite complicated but I'm getting the selection from a TreeView property. Lemme sift through it a sec

private void GetSelection(int selectedID)
{
    if (_nodeTreeView.HasSelection() == false)
    {
        _selectedProperty = null;
        _selectedNode = null;
        _isSelected = false;
        return;
    }

    serializedObject.Update();
    _selectedProperty = _nodeTreeView.GetProperty(selectedID);

    if (_selectedProperty is null) return;

    _selectedNode = _selectedProperty.GetValue<CustomBaseNode>();
    _selectedID = _selectedNode.Data.id;
    _isSelected = _nodeTreeView.HasSelection();

    IsPrefabRemovable(_selectedProperty);
}

public SerializedProperty GetProperty(int id)
{
    var item = (NodePropertyTreeViewItem)FindItem(id, rootItem);
    return item?.Property;
}

After which, this is called:

var selectedPropertyData = _selectedProperty.FindPropertyRelative("Data");
var conditionsProp = selectedPropertyData .FindPropertyRelative("conditions");
EditorGUILayout.PropertyField(conditionsProp);

[gloomy chasm]

If you put a Debug.Log(_selectedProperty.propertyPath); right before the EditorGUILayout.PropertyField, does the path change when you change selection?

[tulip epoch]

Yes, I confirmed the property is being correctly set

[gloomy chasm]

Is this a Editor or a PropertyDrawer?

[tulip epoch]

This is an Editor, but it's trying to draw a property drawer

[gloomy chasm]

To be clear, specifically a debug log right there?

[tulip epoch]

I'll do it again, but I'm pretty sure

[gloomy chasm]

Was just asking because the Layout methods don't work well in PropertyDrawers.

[tulip epoch]

Right, this code isn't in a PropertyDrawer. It's in Editor.

But the PropertyField being drawn is using a PropertyDrawer

[gloomy chasm]

You could try disabling the property drawer for that type just to be sure (just comment out the attribute at the top of the PropertyDrawer)

[tulip epoch]

Hmm, I'll try that. One sec

Yeah it's the same issue even without the PropertyDrawer. It doesn't draw different element until I deselect the entire object and reselect it.

[tulip epoch]

And yep, I threw debug line there and it's correctly being set.

Just not redrawing

[gloomy chasm]

Try calling Repaint maybe?

[tulip epoch]

I think I tried that as well but maybe I put it in the wrong place.

Lemme try again

Nope, no luck

[gloomy chasm]

... try restarting Unity? 😛

[tulip epoch]

Haha I actually haven't tried that xD

One sec

[gloomy chasm]

Also, what version of Unity are you on?

[tulip epoch]

2021.3.21

[tulip epoch]

No good 😦

[gloomy chasm]

Dang, my only advice is the good old start simple and add stuff back in until it breaks. So make a few new class with the most simplest data required for a treeview where selecting an item shows the corasponding serialized property.

Alright, I'll keep looking. This is a editor project that I started two years ago and I'm finally going back to it now. I don't remember if the drawing was working back then, but I vaguely remember it working.

But I also could have changed something and broken it.

[gloomy chasm]

Yeah, got it. Good luck!

im trying to apply a tint to a materialin a neditor tool would anyone know why this is not working, i parse in a color to set the material too when its created essentially i want a specific texture to be tinted/transparent and render ontop of another texture though the commented line here Graphics.DrawTexture(transformedRect, overlayTexture); will render it fully but when i try to tint it or change transparency it still renders it the same way?

    // Create a material using Unity's built-in shader that supports transparency and color tinting
            Material tintMaterial = new Material(Shader.Find("Unlit/Transparent"))
            {
                mainTexture = overlayTexture,
                color = overlayColor ?? Color.white,
            };


            // Draw the overlay texture at the transformed position and scale
            GL.PushMatrix();
            GL.LoadPixelMatrix(0, finalRenderTexture.width, finalRenderTexture.height, 0);
            //Graphics.DrawTexture(transformedRect, overlayTexture);
            // Draw the overlay texture at the transformed position and scale using the tint material
            Graphics.DrawTexture(transformedRect, overlayTexture, tintMaterial);
            GL.PopMatrix();```

Hello, I'm making a simple custom editor to help setup my objects in a specific way in editor, before the game runs. My custom inspector button properly runs game code that sets the objects in a desired way, but when I click the Play mode, the changes that were just made are no longer remembered (its as if I never run the code). Specifically, the values of fields are no longer set right. I'm sure I forgot to call some kind of a "save changes" function, but I have no idea what it is. Does it ring a bell, what should I do? I'm stuck, thank you for your help!

[gloomy chasm]

Check the pinned message (the one with the big "Persist changes" text) 🙂

[eternal slate]

ahh, I had a feeling its going to be something typical 😅 thanks!

[shut juniper]

maybe it's very trivial question, but I can't find answer to why it does it
when I use DrawDefaultInspector (pic 2) - I get this view for SpriteRenderer custom editor like it's in debug mode (pic 1), how can I make to it's default compact view without all the stuff on the component like it's in debug mode?

[gloomy chasm]

You're custom editor for the SpriteRendere is overriding the default Unity custom editor for it. So you have to get the System.Type for the built in custom editor and create a instance of it and then call its OnInspectorGUI method inside of yours.

[shut juniper]

ah, I've found on unity's github this editor, but it's internal by default, so RIP I think 😦
I just want to add a button to enable shadows for renderer, so maybe I will need to use tool menu or context menu instead, hehe

[gloomy chasm]

Type editorType = typeof(Editor).Assembly.GetType("UnityEditor.SpriteRendererEditor");

var editor = Editor.CreateInstance(editorType);

Or something close to that. The type name might be wrong, and not sure on the signature of the CreateInstance. But it is close to that

[shut juniper]

Thanks for pointing me in the right direction for searching! It works!

[warm horizon]

What type of field should I make if I want to select a json file or a xml file for example

[sinful spoke]

is there a way to reprogram the editor camera?
i want to rotate the z axis 90 degrees if im pressing a button.
but i want the editor camera control not to get inverted or whatever i want to have the same camera control.

my puzzle game you can orientate with different gravity rotations each time 90 degrees maybe thats some better explanation

i want to make it easier for my artist to design the levels

[waxen sandal]

You can do a bunch of things with https://docs.unity.cn/ScriptReference/SceneView-camera.html and the other options on SceneView

But I'm guessing htere's no built in way to do something similar to what you're describing

So you might have to take over contorls completely

[sinful spoke]

so i need to write the behaviour on my own completely

[waxen sandal]

I mean I haven't tried something similar, so maybe you can get something acceptable

[sinful spoke]

yeah indeed i need also then to disable the normal sceneview camera behaviour i think

or i want to just add the Z axis rotation

[waxen sandal]

That might be easy by just consuming inputs in OnSceneView

[timid coyote]

what can i exactly pass there? i dont understand (im inheriting from TextInputBaseField)

[timid coyote]

I think i have to inherit TextValueField but still im lost

internal sealed class RichTextField : TextValueField<string>
    {
        public RichTextField(string label) : base(label, 0, new RichTextValueInput())
        {}

        protected override string ValueToString(string str)
        {
            return str;
        }

        protected override string StringToValue(string str)
        {
            return str;
        }

        public override void ApplyInputDeviceDelta(Vector3 delta, DeltaSpeed speed, string startValue)
        {
        }
        
        private class RichTextValueInput : TextValueInput
        {
            public override void ApplyInputDeviceDelta(Vector3 delta, DeltaSpeed speed, string startValue)
            {
            }

            protected override string ValueToString(string value)
            {
                return value;
            }

            protected override string allowedCharacters { get; } = 
                "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890`~!@#$%^&*()-_=+[{]};:',<.>/?";
        }
    }```

[gloomy chasm]

@timid coyote look at the implementation of TextField and then copy it. Though, from what I remember, you can't inherit from TextInputBaseField as it requires inheriting from internal classes

[timid coyote]

i didnt find ApplyInputDeviceDelta, as TextField inherits from TextInputBaseField

[muted cave]

Does a PropertyDrawer not work for an object directly? I.e. I have a ScriptableObject with a custom PropertyDrawer, but Unity keeps drawing it the default way. But if I create a new script with a member of the same Type as my SO it will now work correctly.
I know there are CustomEditors as well, my problem with that is that I only have access to public fields from there.

[dusk portal]

yeah, you want a custom editor

normally you'd use SerializedObject to access the fields so access levels aren't an issue

Hi ! Any idea why setting reorderable to false on a ListView doesn't do anything ? Like, handles are still here and I still can reorder the list.

var providedParametersListView = rootVisualElement.Q<ListView>(name: "ProvidedParameters_ListView");
providedParametersListView.reorderable = false;
providedParametersListView.makeItem = () => { return new Label(); };
providedParametersListView.bindItem =
    (ve, id) =>
    {
        var label = ve.Q<Label>();
        label.text = this.providedParametersProperty.GetArrayElementAtIndex(id).FindPropertyRelative("Name").stringValue;
    };

[gusty mortar]

Looks like [NonReorderable] worked. But I'm kinda confused as to why there's a reorderable option if it doesn't change anything.

Any way to create a time line in my custom inspector that looks like the one in the model import settings animation tab that you can use to preview your animation?

[waxen sandal]

If you make your own 😛

Maybe you can find the reference source and copy it

But it's not reusable

[gusty mortar]

It's a known issue in Unity LTS 2022 (assuming you're using this version) that should be fixed in 2023.x

[dusk bobcat]

I dont know how tho 😔

[rotund perch]

is there any tool that just goes through the unity logs and highlights the links that actually go to your own code? Specifically when the uppermost link just goes to the debug functions interface

[muted cave]

the Volume and Pitch lines are my custom drawers, how can I make the 'Title' align with the other titles, i.e. have the 'Flat' dropdown start at the same x position as the other fields.

[gloomy chasm]

Are you using IMGUI or UIToolkit?

[muted cave]

UIToolkit

[gloomy chasm]

Add the class unity-base-field__aligned to the horizontal container

Might need to add the unity-base-field__label to the label as well

[muted cave]

it's better, but when I expand the window the right side grows more than the label

[gloomy chasm]

What do you mean?

[muted cave]

this is what it looks like when I shrink the inspector down

basically the label is now the correct width, but only as long as there is no extra space to grow into

[gloomy chasm]

Hmm, did you add the unity-base-field__label class to the label?

[muted cave]

ye, and the __aligned to the container. It's like I am missing one of those magic words for the right side of the elements

[gloomy chasm]

You can put all the ones on the right side in a VisualElement and add the unity-base-field__input class to it

[muted cave]

mhh, doesn't seem to do anything

[gloomy chasm]

hmm, last guess is to also try adding the unity-base-field class to the container of both the left and right sides

[muted cave]

The labels weren't actually on the same x position as the default ones, that fixed that but the other problem persists

[dusk bobcat]

why does rootVisualElement.Query<ListView>() return null on line 46?

here is the list view im trying to find

this only happens OnEnable

If you implement BaseField(https://docs.unity3d.com/ScriptReference/UIElements.BaseField_1.html) you get the label and indent formatting for free

Hi everyone I am trying to create an animator controller automatically whenever an fbx is imported into my project and add all animations of that fbx file into the controller.
I am struggling to supply the state.motion field for each of the states in my controller. Since you cannot assign ModelImporterAnimationClips to state.motion.
Currently I am trying to get the animations of the imported fbx file via LoadAllAssetsAtPath but it always returns an empty arrray. Does anyone know why this is just returning empty?

I am doing all of this in OnPostProcessModel

[split atlas]

yo guys how do i install progrids in this version of unity??

[dusk portal]

i'm not sure you can access assets through the asset DB like that in the middle of the import process, you might need to use OnPostprocessAnimation instead?

[crisp temple]

Yeah I was thinking that might be it. Do you know how I can access the corresponding .fbx in OnPostProcessAnimation?

[surreal delta]

progrids has stoped development for a long time, its functionality has been integrated into the engine by default

hi. im making a custom editor for my MusicTrack scriptable object.
eachMusicTrack has a list of TrackStages, and i am putting all of these TrackStage, inside of a list view called stages-list.
is there a way for me to find, and show the loopAudio of the selected TrackStage in the list, inside of the stage-info visual element container?????

here is the code, for the custom editor : https://hastebin.skyra.pw/ajacigexog.csharp
im trying to draw the stage-info panel on line 74

i also want to be able to change the loop audio

[gloomy chasm]

It is a lot easier if you use SerializedObject and SerializedPropert. I tweaked your code to use them so read over it to see if it makes sense.
https://hastebin.skyra.pw/bepozuyiqi.csharp (edited since I forgot to make a change)

[dusk bobcat]

thank you i will check it out 👍

[dusk bobcat]

is there a way for me to refresh everything as soon as loopAudio field of the selected stage changes? is there a callback that i can use?

[gloomy chasm]

You can use the TrackProperty VisualElement extension method. Or if you draw the field yourself you can just register a ValueChange callback to it

[atomic sable]

I have this script (In an editor folder):

[InitializeOnLoad]
public static class GameStartOverride
{
    private const string KEY_NAME = "GAMESTARTOVERRIDE_LOADBOOTSTRAPSCENE";
    private static bool s_override = true;

    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.AfterAssembliesLoaded)]
    public static void OverrideScene()
    {
        if (SceneManager.GetActiveScene().buildIndex != 0 && s_override)
            SceneManager.LoadScene(0);
    }

    [MenuItem("TerraPunk/Override Start Scene", priority = 90000)]
    public static void SetOverride()
    {
        s_override = !s_override;
        EditorPrefs.SetBool(KEY_NAME, s_override);
        Menu.SetChecked("TerraPunk/Override Start Scene", s_override);
    }

    static GameStartOverride()
    {
        if (!EditorPrefs.HasKey(KEY_NAME))
        {
            EditorPrefs.SetBool(KEY_NAME, true);
        }

        s_override = EditorPrefs.GetBool(KEY_NAME, true);

        Menu.SetChecked("TerraPunk/Override Start Scene", s_override);
    }
}

Yet it seems the line Menu.SetChecked(...) is not running in the static constructor, because when the project is opened for the first time the checkmark is not shown yet s_override is shown. Can it just not be ran from static constructors? Or is something else going on?

Wait, I think I misunderstood your original question. Can you clarify what you mean?

[dusk bobcat]

Im making a custom inspector in UI-Toolkit for my Scriptable object called MusicTrack.

Every MusicTrack has a list of TrackStages(which is a custom class) that i populate a ListView inside of the custom inspector with.

Now i want it so that all of the public properties inside of the selected TrackStage inside of that ListView, to show up in a visual element called stage-info.

Thse properties include:
-name -> String
-audio -> AudioClip
-stageType -> StageType enum
-transitionMarkers -> list of TransitionMarkers

I also want the actual TrackStage to be updated according to the inspector and i want to run a the method SegmentTimeline() whenever the audio field value is changed.

[dusk bobcat]

I dont know how to get these properties to show up how i want them to.

The code you sent back then only showed me the name and audio field, and they were collapsed as if they were in an array element, but i want them to show up just like how normal public/serialized properties show up in the inspector

[surreal delta]

Anyone got any good way of applying a global tint the same way GUI.color does for UI toolkit?

And just allow me to modify that file through code

[gloomy chasm]

https://docs.unity3d.com/ScriptReference/UIElements.ObjectField-objectType.html

Or do you mean not allow the object to be changed? If so, just register a value change event, and if new value is not null, set the field to disabled

[dusk bobcat]

can someone help with this?

[alpine bolt]

Tbh I don't understand what you are asking. Could you create a visual representation of what you want?

[gusty mortar]

Is there a way with UIToolkit to get the initial value of a DropdownField for example ? I'm doing a custom propertyDrawer with data binding, but since I always have the default value, I'm assuming CreatePropertyGUI is called before the serializedObject is bound to the property. The only working solution I found is getting the actual SerializedProperty and reading the value from it, but I was wondering if I was missing something in the documentation.

[alpine bolt]

The initial value of dropdownField is either stored by you or read directly from value

When in doubt, just inspect the classes

inspection >>>> documentation

[gusty mortar]

I mean, I'm using dropownfield.value, but it's always the default value, even if my property is set to something else

That's why I assumed the binding is happening later

[alpine bolt]

Is the property a string or an int?

[gusty mortar]

It's an enum, so I guess it's interpreted as an int

Sry, I said a DropdownField, but it's a EnumField. My mistake here

[alpine bolt]

Is your enum value empty?

Something like this```cs
Debug.Log($"Enum: {enumField.value}");
// Prints "Enum:"

Typically in UIToolkit fields, you can only access its value from AttachToPanelEvent onwards

[gusty mortar]

when I read the enum value through the serializedproperty, it is not null and has the right value. The enumField tho', always print the default value I put in UIBuilder

[alpine bolt]

To my knowledge, you can't access a trust-worthy value right after you do BindProperty.

The field will not be synced with the property yet.

I want to show every public/serialized property of the TrackStage selected inside of the list on the left.

Dont mind the picture saying LoopAudio, i want to show all public properties

Where im trying to show this, is in the custom inspector of this scriptable object called MusicTrack

It has a list of TrackStages shown on the left that you can select from, and i want to show and be able to change the data inside of the selected TrackStage

TrackStage is a custom class btw

TLDR:
MusicTrack(scriptable object)
⬇️
TrackStage[selectedIndex]
⬇️
What i want to show:

public AudioClip audio
public StageMode stagemode
public List<TransitionMarker> transitionMarkers```

hi guys how r u. is there any lifesaver here ?
how to get assigned gameobject of an UnityEvent PersistentTarget ?
i want to check getcomponent of assigned gameobject.

when i debug.log GetPersistentTarget(i) it gives me the gameobject name too
so i think there is an access to its gameobject

[willow nova]

Depending on the type, you just need to cast it.
var go = GetPersistentTarget(i) as GameObject; [can be null if its not a gameobject]
and do go.GetCoponent<T>()

[visual tiger]

i've tried casting but it gives me null :

                                var go = unityEvent.GetPersistentTarget(i) as GameObject;
                                Debug.Log(go.name);

[willow nova]

try logging the type -> debug.log($"{unityEvent.GetPersistentTarget(i).GetType()}")

[visual tiger]

it gives me the type of assigned method. i want the name of gameobject

[willow nova]

What was the type?

[visual tiger]

types could be anything. any method of classes

[willow nova]

no. When you debug logged debug.log($"{unityEvent.GetPersistentTarget(i).GetType()}") What was the type it gave

[visual tiger]

its NPC_Waypoint
one of my assigned classes in its unity event
but i want its gameobject (the gameobject that has NPC_Waypoint component and its assigned to the unity event)

[willow nova]

ok. So its a component -> ar go = ((Component)GetPersistentTarget(i)).gameObejct

[visual tiger]

i tried it before but again casting error 😦

                                    if(go.GetComponent<DialogueEvent>())
                                    {
                                        Debug.Log(go.name);
                                    }```

i want to check if the gameobject has dialogueevent component then print the name. but go gives me null

because of casting

[willow nova]

ok

and what target is giving the issue

[real spindle]

You cant cast gameobject to component

But if the type is a monobehaviour then it should work

[willow nova]

 {
     if (obj is Component c)
     {
         return c.GetComponent<T>() != null; 
     }
     else if (obj is GameObject go) 
     {
         return go.GetComponent<T>() != null;
     }
     return false;
 }```

Dont use Monobehavior since Transform isnt a Mono

 if (CheckIfHasComponent<TestComponent>(target)) 
 {
     //has your component
 }```
use case

you can modify if you want to out the compnent that you were searching for

[visual tiger]

its not working because it gives me null and its always false. so it didn't reach to debug.log code (i added)

[alpine bolt]

https://docs.unity3d.com/ScriptReference/Component.TryGetComponent.html

bool checkIfExists = TryGetComponent<Transform>(out _);``` the `_` in  `out _` discards.

[visual tiger]

thanks. it worked. null error was for my own code 😄 thanks a world

Following this since the reorderable option doesn't make much sense (idk if it's a unity 2022 issue or not): if I have an array that is reorderable and inside an element of this array there's another array marked with [NonReorderable] and the reorderable option disabled, the nested array will remain reorderable. Sharing this so that other people don't try to fight with this option that seems to do nothing.

[surreal delta]

it sounds like an issue to me, do a bug report

I just tested this and I'm having no issues. Using Unity 2023.2.18f1

is it possible to write a scripted importer that accepts files with double extensions

e.g filename.tar.gz where the extension would be .tar.gz as opposed to just .tar

while also having a scripted importer that just takes in a .gz

....I have a weird esoteric need for this in my game, just with a different extension

hey, if I have an object that acts as a wrapper to a collection, is there a way to have Odin Inspector show the collection itself without the nested property?

rather than having to expand "Sockets" just showing the values?
